I have an 89 GTA but for some reason the first owner had the hatch replaced with a 91-92 style hatch and spoiler. Will an aerowing install on that style hatch or will I have to do some custom work? I have an opportunity to get a used aerowing for like $60, paints cracking but body is intact.

 

It attaches to the hatch via metal hooks tach welded to the black surround trim

If you can figure out a way for those then go for it

Easiest way is to just swap the whole hatch assembly

 

The aerowing one attaches via metal hooks? I don't have the money to swap out a new hatch. Is there any mounting hardware for the aerowing? When I remove the spoiler on there will there be gaps where it mounts?

 

The hatch feet and 3rd brake light, use bolts. 4 through the hatch to the wing, 2 through to the 3rd brake light, then 2 more from the 3rd brake light, to the wing. The 2 forward tips, use the metal clips. The 91/92 style, should use the same clips on the wing tips.

 

Damn that means I won't be able to mount the center piece without drilling custom holes. That and i'll have two third brake lights. Anyone know if this is possible?

 

Get the correct 85-90 hatch.The clips for the 85-90 and 91-2 ARE different and will not interchange.A 85-90 hatch should be cheap and easy to find.

 

Too bad you aren't closer, I'd do a straight swap.

 

Hey Tenom,why are you wanting to change that spoiler anyways?IMO the on the car looks very good.I know its not an original factory correct piece,but the 91-92 style is far superior to the 85-90 style IMO. The older ones are very heavy,the sun is not friendly with them because they are mostly rubber so they crack and swell.The 91-92 ones are very light and made of fiberglass(I believe) they don't crack and swell,and I have read some posts on here about the aerowing being heavy for more downforce.IMO that really is a bunch of BS

 

Actually, the shape of the 85-90 provides a good amount of down force, good enough for a 307mph stock bodied land speed record set by Kugel/LaFevers with a 91 Formula. they used the 85-90 wing since it works, while the 91/92 is pretty much just for asthetics.

 

OK Zepher,you may be right on that,I don't know. But I think some of us here are more concerned about our cars looking good,and not setting a land speed record of 308mph or more.sorry if I am mistaken on that,but I just don't think the 85-90 gta's and t/a's were originally intended to go 307mph+ .Don't really care if any do either.I just think that Temons car looks good the way it is,and that the rubber aerowings are junk.

 

I agree with that. I personally like the 91-92 wing and put one on my 86 back in 2000,

 

I just don't like the 91-92 spoiler. It's just to small and doesn't complete the rear.
