Having some time at the garage today I decided to move the wheel weights from the outside rim to stick on weights inside the wheel. When I removed the cap to put the wheel on the balancing machine, the GNX emblem fell off..revealing (see pictures) the outline of the TA Firebird in the silicone adhesive on the cap and the firebird outline on the emblem to which the GNX emblem was adhered. I've had the car since 1990 and several years ago I purchased a number of NOS GNX caps and they all carry the p/n 10034896 although the GNX bulletin lists it as 10097569 (interestingly my boxed NOS caps WITH the 12332920 wheel hub cap decal is p/n 10097571). So this confirms what we have heard about ASC using TA caps. It seems to me that a number of years ago GM was caught using Chevy parts on the Cadillac Cimarron and I believe the Cadillac owners were compensated. Is it too late to ask Buick for a refund?
