i found an ad for a Dana 60 rear axle for sale for hella cheap in the paper today, no other information, just that it's a dana 60 rear end and it's cheap and in good condition, i'm going to call tomorrow to find out the info on it, i just want to know if they're worth the trouble to deal with since i can't find a 14bff right now, and also when i call what all should i ask??? i mean what kind of truck it came out from under, was the truck running, what else?? need suggestions please. thanks in advance.
