I have 2 wheels stamped 3699331 and one stamped 3580065 They all are 14 x 6" I'd like to know if back spacing is the same on all 14 x 6 road wheels. I'm trying to locate a fourth wheel to make a set but I don't want to buy a fourth that doesn't match the other three. I've found two for sale but it's a crap shoot unless all 14 x 6" wheels have the same back spacing. Does an E-body with front disc brakes make a difference compared to front drum brakes as far as backspacing is concerned.
