Gut swapping question

[WyattTX]

I like my 85 c10 lwb, but most 4x4s I see are either trashed and over priced. The only cheap ones I can find are blazers. My Truck is a regular cab long bed, and I plan to leave it that way ( I don't like short beds.) My question is: how hard is it to transfer the 4wd parts off a blazer to the long bed 1/2 ton 2wd? Unless I find a lwb 4x4 to do a body swap with, this is my only option other than stretching the blazer frame. Thanks.
