Buying newer truck for donor parts

[craigg1]

Im in the process of buying a 68 Chevy c10. Thinking about buying a cheap 2000-2002 chevrolet that has a 5.3 engine. I would like to be able to use the engine, power steering, power brakes, A/C and possibly the transmission from the donor to put into the 68 truck. Does this sound doable? Im far from a mechanic but wanting to see what my options are and how hard it would be to make the newer truck parts fit the old truck. Any suggestions welcome. Thanks.
