Spoiler door extension
Does anyone know about these side spoilers here? Flat when ending at the squatter panel with a Little piece that mounts on the door? I've heard from some people it was optional and from others it's an 88 only part. Wondering what the true story is. Thanks in advance

Re: Spoiler door extension
Thanks for the reply, I know they're not the best pics but the parts are kind of in storage so I couldn't put them up against my car. These are the ones I'm talking about. Looking at pictures of 87 verts, every single one does seem

Re: Spoiler door extension
Wow, now what's the story on those tail light mounted trim pieces? 87 only or part of a complete package with the door extensions?

Re: Spoiler door extension
My '87 is a sixth digit 3 car and I don't have those taillight fins. Mine has the small middle taillight which I have heard are the earlier versions, but it's hard tellin with ASC. It also has the 20th Anniversary Commemory Edition dash pouch also. 5.0L, TPI, 5 speed car.

Re: Spoiler door extension
A friend had those door pieces on his 88 Camaro but I'm unsure of the build date.

Re: Spoiler door extension
If I had to guess, I'd say the pieces by the tail lights were their solution to covering the holes in the quarter panels for the regular lip spoiler. Cheaper and easier than welding the holes and painting the car.

Re: Spoiler door extension
I'm only going to refer to VIN 3 cars. Spoiler door extensions were for the 1987 model year only, BUT ASC still had some stock left after the model year run, so they used them for 1988 convertibles until they ran out.

Re: Spoiler door extension
Since I've had mine since 88 I agree. ASC factory cars. My vin has a funny 9th digit that isn't in the decodes that I have found and that letter is "X" and I am kinda assuming that meant send this car, before the top is assembled on it, to ASC for conversion and the 87's like mine all had the door extensions. My wifes doctor drove a 88 vert and it didn't have them on it. Just MTC.

Re: Spoiler door extension
So if you DO have a 88 then it is a very early 88.

The 9th digit is a check digit... it is not hard to calculate, but without a computer it takes a min or two. Check digits can be any number from 1 thru 9 and they can be a 0 (zero) or an X. More or less you give weight to each digit position within the VIN and each letter is given a numerical value, for example an A is worth 1, a B is 2, but a J is also worth 1, Some letters are not used like the Letter I, O or Q. Each position in the VIN has a value, and then you multiply the value of the number and the position value, then You add all of your calculations together then divide them by 11. If you have a remainder of 10 then that is an X, a remainder of 1 is 1, a 2 is 2 etc...

85-88
89
90-91
92
The later 89-92 are wider in the rear than the 85-88
The trunk pieces changed mid 1991 to just carpet, ( all 91-92 Firebirds got the carpet AFAIK) but the Camaro started with the plastic pieces then went to the carpet mid year, around Aug of 1990 or so I think.

Re: Spoiler door extension
Yep those are the quarter panel cover trim extensions that all 87's came with and the early 88's. Then they were never used again. IMPORTANT NOTE: the long trim pieces that go on top of the quarters that would meet up with these little "spears" are different on the sets that have the spears vs the sets that didn't. The sets that came with the spears are more squared off and those that didn't are more rounded. I have a couple sets of each. Also note, these quarter trim cap pieces getting dry and brittle over the years and get spider cracks in them. Don't just fill those cracks and sand them and then paint your car. The cracks WILL come back right thru your brand new paint. Yep, learned that the hard way

Re: Spoiler door extension
I want to think it was an 86-87 offering, and the early early cars in 88 might have had them until they ran out of them...

Re: Spoiler door extension
someone should scan these for 3d printing.
I think these would be a good candidate.
especially since they are hard to find parts.
later,
Chris

Re: Spoiler door extension
They would be kind of difficult to 3D Print. They would have to be made from ABS. It would be easier to make molds from them and then duplicate them with fiberglass like the originals.
