Default Rear Wilwood Disc Brakes interference with Weld Wheels

I just completed an update on my back half 1980 Malibu Bracket car.

I went to 35 spline Strange axles, spool, and 5/8" drive studs for the wheels. Also replaced all bolts and heim ends. And had 9" rear end and ladder bars powder coated.

Last item is, I changed from drum brakes to Wilwood Disc brakes. I used kit # 140-0261. I have Weld Alumistar 15"X 15" rear wheels with about 7" back space.

The problem is the outer radius of the brake calipers and the inner radius of the wheels are about the same and rub each other. The wheels won't even turn.

I called Wilwood and they said there is no brake with less radius and I need to change wheels.

I looked at a buddies car tonight that has Wilwood disc brakes and he has 1/4" clearance. But he has much less back space on his wheels.

Any one else have this issue??

I know I can grind/clearance the calipers some but hate to cut on brand new parts.

Wilwood also said .060" clearance is enough, but stopped short of agreeing grinding is OK.
