I know one of my Buick brothers has all the information on the correct mounting of the rear spoiler on a 72 GSX. Looking for placement, hole location and all I would need to know for a correct installation, Thanks!!
Go to Todd's. Not only does he have the correct mounting components but I also believe directions are included. Tom T.
If you look at the rear spoiler it had a crease that matches the trunk angle at the back and they are centered on the car. http://www.buickperformanceclub.com/rearwing.htm Mark
The braces slide in the larger holes that are drilled in the bottom of the trunk lid so you can put in the nuts and bolts. Duane
