Another question would be are there any differences between the stock B,C and truck spindles?
Yes, There is a big difference. Only certain "C" body cars use the same rotor and bearings but the ball joints are different, like a 73 Fury, "B" body cars use a completely different ball joints, spindles, wheel bearings and rotor. Plus the steering arm from the truck will not bolt to the "B" spindle. That's a few things I found out.
