Having just done that swap my self there two different sizes and one is exactly 7/8 longer than the ones OldWolf uses so be careful when buying them. They could be used but you would need a spacer block for them to work. I did not like the look of the block on top of the frame. They were marked to fit 63 Chevy at the wrecking yard. Being I put a HEI Dist in I also moved the mounts forward 1 1/2" to clear my HEI from the firewall and you will still have plenty of room to mount your fan or electric fan and the 4 core radatior.
