I have a chance to buy a Dana 60 from a 1970 B-body. Internals are all rebuilt with 3.54 gears. Comes complete with brakes. Just needs to be painted. The guy wants $2000. delivered. I don't need it now but may in the future. I don't want to tie up the money if I can't get it back if I wanted to sell. What is the going rate for these things?
