2wd to 4wd help

[rgreathouse]

I have a 1972 c10 2wd long bed straight six (leaf spring rear)...I can get a 1979 one ton 4x4 single rear wheel with a good running 350/400/205 for $700 from a friend. I am trying to figure out the best way to convert my truck to 4x4.

Here is what I am planning on doing please review and tell me what you think.

from what I understand the front body mount on my 2wd frame can be replaced with the body mount/spring hanger from the 4x4... I can mount the shackle mount from the 4x4 onto my 2wd chassis and run the 1979 leafs and axle. keep my 2wd steering box and run crossover steering.

In the rear since I currently have leafs I should be able to just swap leafs and axles out

For motor/trans/t-case will the 79 crossmembers/mounts work on my 72 chassis?

thanks for any help hopefully this doesnt get too confusing
