I am looking to buy a donor truck for a couple of projects. I am planning on buying it from a junk yard. I need the axles, engine, and transmission. I plan on doing a full rebuild on the engine, and probably the transmission. On the axles, I will replace whatever is needed. The only thing I am worried about with buying from a junk yard is getting it home to find out the block is cracked or the transmission is complete junk and not rebuildable. I could try to buy one from someone, but finding one with all the parts I need is much easier at the junkyard. Any advice?
