521, 620 differences

Nuts, and bolts. On my PL-521 pickups, the engine uses metric fasteners, the body uses SAE fasteners. What are the body fasteners on a 620?

Example, I recently replaced the rear wheel cylinders on one of my PL-521pickups, and the replacement cylinders had M8x1.25 nuts on them. the old wheel cylinders were 5/16x24

Also, I have a L-18 block, and the PCV pipe that comes out of the engine has a smaller diameter than the pipe from a L-16.

Obviously I know the body has differences, but actually my question is, what is the same, or at least functionally the same?
