3/4 ton axle swap for K5

[madman 72]

I have a 75 K5 with the dana 44 front and 12bolt rear. I founda 82 3/4 ton chevy that i can get the axles off of and plann to do it soon. Question being what parts do i need to get off the 82 axles drive shafts ...Should I get the tierods and steering box ? What other parts should I get off it to complete the swap. Is this a direct bolt in or will i have to modify a little. Will the drive shafts work with my existing tranny and transfercase, Granny fourspeed on K5 and the 82 NP205 on K5 and I think a 208 on 82 Should I just cut the axles to fit .if they will work.The guy said take what ever i needed. Any info will be greatly appreciated.
