Parts swap with 2001-2002 Silverado/Tahoe

[craigg1]

Ive been thinking about buying a running 2001 or 2002 Silverado or Tahoe with a 5.3 engine and a 4L60E transmission and using that to put into my 68 C10. I can find one in my area with about 150,000 miles for about $3,000-3,500 and just replace some parts. Not sure if I want to go this route or if it would be cheaper to just buy the engine and transmission cheaper by themselves.

My question is, if I buy the whole vehicle, could I use the A/C parts and the disk brakes (and whatever other parts) from the Silverado or Tahoe for my 68 SWB truck? My truck is not an A/C truck, but would want that at some point. Any thoughts or suggestions welcome.
