Hi guys
as seen on classicindustries there is a different part number for the door glass for 82-89 and 90-92
what is the difference, only the colour?

thx, Rene

 

Only difference I know of is that A01 Tinted Glass was an option from 1982-89, but was made standard equipment for 1990. The vast majority of 1982-89 cars had the option though.

 

Pretty sure the difference is in the door window hardware; including the small parts that normally come attached to the glass.

 

/\ yup they changed the regulators in the doors in the later years. 82-92 glass will work in all years , there will just be a few extra holes in the glass

 

For future reference:

I've converted window systems when building cars in the past and since I'm going to have to replace the door glass in my 88,.... I wanted to take some pics to show the parts needed to convert from the 'early' system to the 'late' system.

The RED circles shows the white plastic push-plug as installed in the factory door glass from 82-89. ( I was never sure of the cut-off year ! ) These plastic inserts are located where the window touches the "door felts" supports at the top of the door. The BLUE circles show the plastic (?) 'hooks' that are used in the 90-92 door system. These are held in place by Torx screws and a metal retainer,..... SOAK THEM with some PB-Blaster before attempting removal !






These 'hooks' interlock with the window felt supports when the glass is fully raised; even the felt support itself is wider than the first design,..... makes the glass much more stable than the 'early' set-up.



At the front of the door - and door glass - there is an up-stop. The 82-89 door glass has a basic 'contact' up-stop riveted in place,... but in 90-92 another 'hook' was added using a Torx screw to secure it. The door bracket also acts as a 3rd door-felt as the front 'hook' interlocks with it.



I picked thru the door glass I've got and found 2 decent windows today. If I find any other pieces I missed or learn of any other missing info about this conversion when I install the replacement glass,............ I'll update this post.

 

Dang, I pulled a door glass out of a junk yard 1989 Camaro but it has the 90-92 style front hook I guess. So I need to swap over my front "stop" style piece to the 90-92 glass and I am good?

 

I'm following too. I find window pictures/diagrams etc. etc. hard to come by. I bought a rebuild kit but frankly I don't know where all the new parts go. ....I'm not currently working on this, but I know it's coming!!!!

 

Bump

 

I havent paid much attention to the parts I pulled from a set of 91/92 doors to put in my 88 but my 88 doors had been gutted. I picked up a set of earlier doors to get the manual regulators from and have everything installed back into the doors except the glasses as I was waiting to install them after paint.

I guess my question is, if everything is matched parts from the 91/92 doors except the regulators it should all work together in the 88 door shells with the earlier manual regulators?

 

I don't have an answer for you guys, but only another possible variable...
I received my new glass recently and found the holes aren't the same compared to the original glass. Has anyone seen this or know if the different years had different locations for these 'hooks" and the front "stop" or was my replacement glass manufactured wrong?
The pics show the mounting location holes to be correct, but the holes for the plastic pieces are off. With the drivers glass in and all the way up, you can see the plastic hooks from outside the car. In this position the front stop is still about a 1/2" away from the stop giving you the idea the window ISN'T all the way up.
This is for an '89 IROC and both my doors use the "hook" style you guys show above. My drivers side is a '92 door. The passenger side is original '89.

 

@KCG what manufacturer door glass did you buy?

 

I don't know the manufacturer, but I bought them at Eckler's/Ricks Camaro.

 

Bump .. Has anyone seen this before? Replacement glass holes not lining up
Is this correct for the 2 different years/styles of glass or is mine manufactured wrong?

 

I'd have to see if I have my pics still but you won't get much help on here, at least I didn't. I found out that you end up plugging 2 of the holes and I had to relocate the hangers on my 88 using an 89 glass. It was very confusing but I got it squared away finally.

 

Thanks for the reply. I understand the hardware is different between the years, but my question is, are the HOLES in the glass in the same location for both versions?

 

For what it's worth,.... I do not recall any difference in the glass holes when I converted my 88 doors to the 92 style hardware. I used all factory original parts.

I do not have access to door glass in order to investigate / confirm anything for you, just wanted to add my ----> again: for what it's worth !

 

Thanks John for the reply. I'm hoping someone does have both years of glass and can confirm hole location.
Meanwhile after talking with Ecklers, they couldn't confirm that any of their glass was any different then what I received and didn't really seem interested in investigating. It was basically send them back and we'll refund your money. We'll see.
Where to next, Classic Industries?

 

I bought new door glass for my '84 TA last year from Jeg's. It took FOREVER for me to receive them - like 6 months. I haven't installed them yet so I'll try to take some pictures this weekend laying the new glass on top of the original. I didn't think to check but hopefully all the holes line up. One of the windows is still in the box so I can also tell you who the manufacturer is.

 

Nutro, do you mean you simply put your '88 hardware on the '89 glass and it worked?

As noted above, I purchased from Eckler's/Rick's Camaro. Their part#'s are EK-xxxxxx. Interestingly enough I noticed a sticker on the passenger side glass DD6419 (see pic). Looking at Classic Industries website, their part#s for this glass is FD 6419 & 6420.

 

Still haven't been able to 100% confirm if my glass was defective or not with anyone, but I sent it back and received a refund.
I'm going to try Classic next and see what happens.

 

(I responded to you in my thread also, for the glass issue I had) If you order from Classic, get the 82-89 style...it will fit all of your hardware, even if it is 90-92 model years. The 82-89 just had an extra hole at the front, that you will not use for 90-92. All hardware will transfer and line up with everything.

 

I wonder how many places actually manufacture the glass for these cars...
I first purchased 82-89 glass from Ricks/Ecklers and the holes for the stops didn't line up. (pics above in previous post.) Ecklers has their own part #'s but I did find stickers 6419 & 6420 on the glass from them. Same as Classic/OEM uses.
I already sent it back and ordered 90-92 from Classic. Received it yesterday and the all the holes line up but it does seem to have a curvature issue like you had.
Now I'm stumped. Guess I'll try it and see what it looks like in my car.

 

Prior to installing..just lay the glass over the same side glass that you knew fit properly (the glass that was originally removed)...If it lays nice on it with minimal/no gaps at the edges..go for it!! It is possible that I just received defectives from a production error...mine was way off. But if you lay your new 90-92 glass on top of the original that you removed...don't even bother trying to install it if there are large spaces around the edges. Glass is molded, should be nearly identical...i.e. like two cups that are identical fit inside each other. I tried like hell to get mine to fit...and I even got them to the point where they sort of fit, but if i put them down, on the way back up it would bind really bad on the rear/sail panel weather strip...so I would have to open the door, put window up, then close door...I knew it wasn't right, and it did not sit straight with the outer glass run weather strip either...was too curved. I can't explain why the holes from your Ecklers glass were not lined up properly. In my experience (I have had 6 thirdgens, over the course of about 28 years..3 in which I swapped glass..no issues with first two), the holes from 82-92 were all in identical positions, with the only difference being the extra hole in the front that doesn't get used on the later models. Just saying...definitely lay new glass over your original before attempting install!!

 

I had to try anyway and you're right, it doesn't fit! The 90-92 glass is bowed such that at the front and rear its against the inside of the door, and I mean scraping metal, while the middle is jammed against the outside sweep.
Here's one pic of the new lying on top of the old. And this is just resting on it, I'm not pressing it down tight on the other end and its still this far off.



Back on the phone with Classic, and I'm getting the 82-89 version next. I hope theirs is different than Ricks.

 

That's exactly what I encountered...must either be a bad run, or the mold/spec they are using is way off. I would like to mention that Classic Industries and their technical department were very helpful, and provided full refund on the defective glass. Yes, I wish I didn't have to go through all that for something so seemingly simple..as I had swapped glass on other cars with no issues. The 82-89 glass from Classic dropped right in (yeah..you really had to fight that 90-92 piece, because of the extreme curve...middle glass would press on outer run, and the front/rear would curve inward)...when you get it, you'll notice a big difference...and I had no issues with the holes for the hardware, as the only difference was one extra hole you will end up with that does not get used.

 

The 82-89 glass shipped yesterday. We'll see when I get it.
Did they give you an RA# to send the 90-92 glass back?

 

Yes, Classic did provide an RA for the return. Then I purchased the 82-89 glass, and was refunded for the defectives/shipping when they received them. There was a minor cost difference..I forget how much though.

 

So to update this saga I received another set of glass from Classic Ind for 82-89. It fits! Mounting holes line up and I see no issues with it mounted loosely so far.

As 1989rocg92 said above, Classic tech was very helpful and took care of all the shipping back & forth. They are stumped as well on the 90-92 glass and evidently have decided it was a bad run. Shortly after suppling an RMA to ship it back, they cancelled it and said "never mind, we don't want it back". That told me they realized they had a problem with this glass. Wasn't worth it for them to ship back glass they couldn't resell.

BE FOREWARNED! Just use the 82-89 glass

 

So, I am going to respectfully add my 2 cents to this thread:

I have a 1991 Z28 w/305, restored to stock over 10 years ago. I've been wanting to replace the original door glass because it's all scratched up and water etched from the previous owner. Decided to pull the trigger last month.

Based on reading here, I bought the 82-89 glass from Classic. The glass received matched my existing glass in shape, it had (2) extra holes as noted in previous posts, but (2) of the holes I needed for my hooks were drilled about 1" too high, and if installed would prevent me from raising the window up all the way.

I called Classic. After being chastised for not purchasing glass for my model year, lol, I was able to return the glass (shipping at my expense) and bought the 90-92 glass.

The 90-92 glass arrived today, and it matches my existing glass 100%.

 

oh wow. What a crap shoot!
I'm glad the 90-92 glass worked for you. What a PITA!
