Question about trans ams. I was under the impression that all trans ams starting in 1986 has the wrap around wing, but I see several like this car with the short spoiler. Was that a factory option, or has this car has a spoiler transplant?

I've got the older spoiler. I think there was something wrong with the tooling for the new one early on.

 

since I posted that I read a couple of places that all 85's got the short wing, and 2nd half of the 86 year is when they changed to the wrap around. Mine is still in decent shape, surprisingly enough...

 

Ask for the RPO codes if you want to know if that car came with the aero or D80 wing. Reason why I state that is because that car shows some modifications. The hood louvers are painted black and that's not factory for a red car. The bird on the front bumper cover looks too big but that could just be me because even that rear wing looks odd. If stock, I think that wing should be red to match the primary exterior color.

In 1986, you could get the aero or D80 wing. If the car originally had the rear window shade/louvers (DE1), that would also be a factor.

 

For 86,the Wraparound Spoiler(Black) was Standard and the Spoiler shown on this car was available as an option but only as matching color

 

1985 was actually the first year for the wraparound spoiler.

 

I need to check my 85 parts book, but that goes against what many sources say

 

Common knowledge says it started in 86, but there have been a few 85s people have posted here (documented) that had the wrap wing.

 

That's interesting

 

Option in 1985

This pic is from my 86 brochure,notice the areo wing as Standard.

 

maybe JT was onto something when he said the old spoiler may have been used when factory louvers were purchased

 

With the D80 (straight wing as pictured in the eBay ad) as Available. Meaning the Aero (D81) or Straight wing (D80) could be had on the 1986 Trans Am. While I believe the D80 was required for the rear shade, I believe it could be ordered alone.

But if you look at the 1986 order form, it states that the D80 is "N.A." on the Trans Am.

 

 

What printing is your 1986 sheet? Mine does not show the DE1 requirement on the D80. That's just something I learned over the years. Mine just notes D80 is N.A. on the Trans Am.
