picked up an 86 glx a while back. bought some wheels off a friend a few days ago and i cant figure out what they are.. he said theyre stock rx7 wheels but i cant find anything about them. he only had 3, the set is missing one of the rears, but i only payed 30 bucks so i figured i couldnt go wrong. any help would be appreciated. the fronts are 15x7, and the rear is 15x8.
