i used to own a 72 chev 1/2 ton but it gave up the ghost a long time ago. now i got a 91 chev 2500 4x4 but the bottom end is in pieces. it had two blown head gaskets and the gaskets were changed. they started to work on the bottom end but life caught up and it was given to me. no bed on the truck. the oil pan is off and the bearing caps are off and it is cold outside where I am working. i need to clean my garage out so i have a cement floor to work on but i have very little to pull it with and it has been sitting for a few years.
