When I rebuilt my '88 Formula in 2013, the stock hatch had some serious rust and the wing was shot, so I grabbed a base hatch and wing from a '91 bird. Painted it with the car.

Fast forward, I've acquired a fiberglass 1988 style aero wing. If I remember the bolt pattern is significantly different.

My car is locked up in the trailer, but I was curious for those that have great memories, if I pop the plastic caps on the inside I should have the spots to drill out for the gta/formula/aero wring, right ?

Then I just need to weld the other holes shut. There is no change of the base of the wing covering the other holes, right?

No clue on the earlier cars, but on the 91s the holes on the inside of the panel are in different spots to correspond with the holes in the exterior.

 

On my '89 there are spots for both patterns of spoiler. I went from a destroyed aero wing to a regular pedestal style.

 

You mean under the hatch? So you just drilled out the second set of holes ?

Yes. On the underside of the deck there are plastic plugs that cover the bolt locations for the other type of spoiler.

Measure, eyeball, measure, eyeball and then measure some more. The locations for the bolt holes are very generous and oversized so it will be up to your measurements and care in regards to how precise you will be when locating the new spoiler.

I checked everything about 30 times before I drilled and still got mine misaligned by almost 1/8" to the passenger side. Luckily it's not noticeable unless you are REALLY looking. Turns out the spoiler itself isn't exactly symmetrical, as in the "wing" part wasn't exactly dead center on the pedestals.

 

Hrmm. good to know. I wonder if it would be better to just drill larger holes so it can have some adjustment.

I gotta figure out the clips for the sides. Looks like it has some aftermarket side clips specifically for the glass wings.
