The Jimmy is most likely leaf springs since it is first a GMC and second a 4X4. The C-10 is likely a coil spring truck. If I guessed right, then you will have to cut off the spring perches and weld new trailing arm perchs back on. The shock mount should be the same I think. I think several of the board venders can hook you up with the trailing arm perches.

Getting a air locker would be way worth the effort. Wish I had one.
