Underdash plastics
I forgot to ask about this. In May, I went to the Fbody Gathering in Atlanta. My car was judged and I was informed that I was missing the underdash plastics. I've spoken to a few people that have commented that they only had one side or that neither side was on their car either.
I'm looking for original owners that know for a fact their car had 'em, didn't have 'em or was only on 1 side. The thing that has me wondering is, the plastic cover is what holds the underdash courtesy lights in place, right? My car has a metal bracket on both sides that holds the light. This is what makes me think my car never had 'em. Please let me know.

To my knowledge, those are called hush panels.
I have them both on my 89, but then I'm not the original owner, so they could've been added, but at the same time, I have no metal brackets. they mount directly into the plastic hush panels.
For the record, I'm interested in figuring this out too.

I bought an 85 Camaro back in 86--car had 10,000 miles. Car was a stripper--4cyl, rear defrost and auto trans w/the ers radio--that was it. Car came w/no hush panels on it.
I think it probably came like that since I don't think anyone would bother taking them off.

Scott,
I know without a shadow of a doubt that 1987 and 1988 IROC-Z's with the 350 did not come originally with the hush panels. I do not know the reasoning. Weird.
Like your car has, the courtesy light bulbs are mounted on plastic "L" brackets on these cars only.

Boy Willie,
You must live and breath these cars, particularly 87's.
My car has the panels, but no courtesy lights, because I don't have that option.
My buddy's 87 with a 350 doesn't have the panels but has the lights.
Go figure

87s, but only Camaros!! My favorite year.
One other point I neglected to mention earlier. When equipped with the hush panels, the ALDL connector is covered by a flat, rectangular black plastic plate (below left) that snaps onto the hush panel. On 350 cars without the panels, the connector is covered by a form-fitted, black plastic cap with print, "DIAGNOSTIC CONNECTOR" (below right).

Thanks Willie. Now I don't need to spend the money to find these. I'm very impressed with what you know.
The reason they changed the cover was because the plastics covered the plug and the flat cover was just an access door to the ALDL. Without the plastics, the plug would be fully exposed and the form fit cover would protect it. Below is a pic of the drivers side and passenger side under my dash. No plastics, but the lights have a bracket.

Both my 84 Z28 and 89 TTA have those panels on the car.
Memory is a little vague, but wasn't there a quiet group as an option? Maybe part of that option package.

I have an idea. Scott's pics helped to form this idea. Maybe, just maybe the hush panels can't be installed with those Delco Bose front speaker kick panels. I know the '87 350 IROC-Z (I used to own it) and the '88 350 IROC-Z both had Delco Bose. Maybe it's NOT a 350 connection, but a Delco Bose one instead...... Now we need to take a poll of guys with the original Delco Bose system I suppose.

My 87 SportCoupe didn't come with hush panels, but Moms 92 RS & my Bro's 84 Berlie did... I was going to suggest that maybe it was part of the custom cloth interior? I have since added the hush panels on my car.

My car is fully optioned. It has the custom interior and also was upgraded to leather. I'm beginning to believe Willie's theory that it might be related to the Kick panel amplifiers.

My car is a 83 L69 (duh) Z28. It has the optional interior and upgraded radio for that year, but not the one that swings out.
It has the hush panels on both sides, with courtesy lights.
My ALDL is covered with the plastic cover, seems like it has "Diagnostic Connector" cast into it.
Being a 83, I don't have the RPO list, so I don't know what sort of packages it might have been equipped with.
I can snap some pics later on if you want them.

My 88 IROC-Z has the "hush panels" and it does have the Bose sound system. I believe them to be correct because the lights mount in them and the car has not been hacked up or anything has been changed.

It appears that there was no standard for having the hush panels. I think we've determined that it had nothing to do with the Bose setup in 88 on up cars, but we haven't heard from any other 87 Bose owners. Also, have we determined anything regarding engine size yet? That was Willie's first thought.

My 88 IROC-Z with ERS has the panels.
Yes, but ERS was practically any optional stereo, not necessarily the Delco-Bose. Do you have the DB system?
It seems funny that the factory couldn't just have a seperate panel for the Bose systems to fit the amps.
GM has always been cheap....
Also, have we determined anything regarding engine size yet? That was Willie's first thought.
So far, the results are consistent: 350 = no panels. We need to hear from more 350 owners. Scott, why don't you start a new thread calling out 350 owners. Then post your pic(s) again to illustrate how a "no-panel" car looks like. I bet you'll get a much better sampling.
BTW, I have not stopped at Dirk's house yet. Stay tuned on this....

both of my 84's (sport coupe and z28) have the panels. they're roughly 2 months apart in production, and both have the upgraded interiors with the custom cloth and adjustable headrests.

i have an 87 z28. not bose, 305, and i have the light brackets and no hush panels. i tried buying som but it restricts the movement of my foot from the gas to the brake and it also didnt mount right. the passenger side is fine but i am going back to just the brackets.

My 87 IROC has Bose speakers and underdash panels. Car was built in Jan 87 in Van Nuys.
I will attach two photos. One with this post, and the other in a following post.
A bulb is present in the socket, and is believed at this point to be a factory-installed original bulb. The bulb lights, but light does not reach the floor.

yes. Look at the picture of mine above. You can see the bulb and socket are the same. The mount is the only thing different.

willie, a friend of mine has an 87 IROC 305 TPI with the BOSE kick panels. next time i talk to him, i'll ask him if he has those panels, and then see what he says. i'm pretty sure he did have them, though.

Just helping the cause:
Previous 84 LG4 sport coupe with no hush panels. I never found the RPOs for it, but it came with A/C, U79 audio package, manual windows locks & hatch, and no courtesy lights on the floor, under the hood, or in the hatch.
Current 86 LG4 sport coupe with both hush panels. Here are the probably relevant RPOs:
TR9 : 76-88 : LAMP, GROUP
UM6 : 76-88 : RADIO, AM/FM STEREO, SEEK/SCAN, AUTO REV CASS,
UP8 : 76-88 : STEREO RADIO INSTALLMENT PROVISIONS
U25 : 76-88 : LAMP, INTR, RR COMPT, COURTESY
U26 : 76-88 : LAMP, INTR, ENG COMPT, COURTESY
U29 : 76-88 : LAMP, INTR I/P, COURTESY
U79 : 84-88 : SPEAKER SYSTEM, 4, DUAL FRT COAX, DUAL EXT RGE PKG
YE3 : CONVENIENCE PKG, DECOR LEVEL #3, HIGH TRIM
YT9 : OPTION PACKAGE, FISHER FURNISHED PARTS

My 86 Firebird 2.8, stripped down to the only options it has is Air and cruise (not even delay wipers) with the old AM/FM non cassette radio has the hushpanels, but only has the light on the drivers side with a place to put the bulb, the provisioning is on the passenger side for a light, but it is not there. So there's another funky setup that GM did.

My 87 TA has the panels on both sides and has the courtesy lights on both sides. I took the one off from under the driver side since my shoe always seemed to rub against it.

sure what are you looking for, radio codes, interior, engine? I don't think there is a special code for hush panels, but i could be wrong. I'm not on my home computer now so i can't post a pic of it if you don't believe me. But i can later tonight.

I know for a fact hush panels didn't come with the bose system because the pass. side hush panel light will smash against the bose kick panel & melt the carpet on it lol.
I've tried this once when I swapped interiors and my friend had the bose system, he did not have the hush panels. I did.
