Anyone know if these will fit? my 86 Cutlass
Weld racing Pro stars. 15x4 fronts and 15x10 rears with 7.5 inch back spacing, lug pattern is Chevy 5x4.75

7.5 Wont work except with adaptors , you need 4.75 to 5.0 for rear 10 wheel on gbody.

I would look for a different set of rims and for the back I would go a 15 x 8 or 8.5 with about 4" of backspace unless you plan on doing a frame notch.
Also Cutlass wheelwells are not round which can also affect wheel fitment with wider rims.
A 15 x 10 will have issues with either the tire rubbing on the frame or sticking out of the wheelwell and I personally don't like using any adapters or spacers to fit a wheel to a car.
And on a 10" wide rim even a 1/4" off on the backspacing will make a difference.
