Riddle me this:

I have a '53 3/4 ton GMC where I am converting the front brakes to discs using the Rustic Brake kit along with replacing the D52 calipers that came with that specific kit to Wilwood dual piston D52 calipers. Everything fits as it should however, when measuring for wheels, I found the driver side can take a 16" wheel but the passenger side would not as it would need a 17" wheel. Using a carpenter square I measured from the center of the spindle to the outer edge of the caliper, 8" will clear driver side (16" wheel) but passenger side is more like 8 3/8 to 8 1/2" (17" wheel).

I couldn't figure out why, got frustrated and came in for dinner.

any ideas out there?
