    I have a 98 C1500 2wd and plan on a swapping my rear axle for a 6 lug conversion and found a rear axle that I haven't measuered yet that came off of a 73-87 chevy truck. What problems will I come across when doing this swap? Main concern is that the spring perches and shock mounts won't line up.

    The spring perches and shock mounts won't line up for sure. The overall width may be totally off as well. Have you measured from backing plate to backing plate? I'm pretty sure that 73-87 is a narrower axle overall.
