72 GMC swap q's

[JibSheet]

I have a 1972 gmc with rear leafs, 1/2 t, a/t, 2wd.

I have a 1967 chevy 3 quarter ton 4wd donor truck. I want to keep my 72 frame for the power steering and frame quality so I can't just move the body over.

Since my 72 already has rear leafs, how difficult would it be to swap the axles / springs and brackets over from the donor truck to mine? Like I said, I would rather keep the newer frame, wouldn't this be a matter of bolting in the new parts with out too much hassel?

Thanks for the help!
