The Richmond gears come stamped with an actual pinion depth number, a number that can be obtained by using a dial type pinion depth gauge.

Ford gears do not come stamped with a pinion depth number. They are designed to be installed by using the Ford pinion depth gauge T79P-4020-A. You basically shim the pinion until it touches this gauge, it has no numbers on it.

Many people have had luck swapping the gears and reusing the stock rearend shims when using FMS parts. This is definatley not the right way to do it though.

A properly set up gearset will have proper pinion depth, preload, and backlash. All of those require special tools and experience to obtain.
