I put this car together back around 1985-1987. If you bought this car, I've got some old pics you might be interested in. http://www.easttexasautos.com/search/1970/Buick/GSX/446670H2289831111/Cars_and_Trucks_in/Texas/
That speaker was there when I bought the car in '84. I actually kinda liked it. So much that I've thought of doing something like it to my SC. I've even got a grill assembly from a Rivy ready to go.....
Looks like the car also went thru Mecum Houston last month: http://www.mecum.com/auctions/lot_detail.cfm?CFGRIDKEY=HA0412-129700 Their add says the car's only had one paint job. Not true. Was originally Gulfstream Blue with white top/interior, was red with white interior when I bought it. Was white/GSX with white interior when I sold it in '86-'87. Anybody pick this one up?
