Make sure the ratio's match. Other than that the conversion U-joint should be needed for the companion flange/yoke

the ratio shouldnt be a big deal if im swapping both axles i would assume. i just wasnt sure if there was a different mounting or anything. 

are the spring mounts for the 4 wheel drive 1/2 ton trucks the same between 78 and 87.
