in good faith i purchased a set of gnx rims from a board member for a customer of mine.after 1 month the customer came back enraged telling me they werent gnx rims but from an 89 tta.the 2 rims marked rear will not fit the rear and the offset makes them hit the frame.also there is visible gold paint under the black.i returned him his money as not to tarness my reputation with the local buick crowd here.i sertainly had no idea.does anyone know the part numbers or the exact identifying of the real thing?i know the rear is the same length so it appears ive been taken for a ride.
