c bushing measurements

[deerecrossing]

im putting a 78 bronco axle under my 95 f-150 and im ordering cage arms. the guy told me that i had to use c-bushings for that cage arm but i thought any c-bushing would work for em. also how do i know what degree bushing to get?

you want know until you get it all put together. then look at the pinion angle . i would start out with some 2degree bushings because those cage arms already come offset .
