Best bet is to call them. They are familiar with our cars. No, the parts are different on the F150. I have yet to see an M5R2 that needs new bearings.
I have used both Ford parts and from SG. I can tell you that the Ford seals are much better quality even though they cost 2x as much they are worth it. The brass blockers from SG are about $15 ea and the fibre are $45 ea. The stock replacements from Ford are $25 ea but they are discontinued so good luck finding them.
