I have a 1993 GMC 3500 that is in extremely nice shape. It has a 4.11 rear diff and a 5 speed standard transmission. I am giving it to my daughter's boyfriend and we plan to replace the 6.5 diesel wit...
Good Luck Terry. My real question though is what was wrong with the original 6.5 :W Oh wait Bob has one that is still running so they must all be good.... I think your on the right track about the cooler. Might as well do it once and be done with it. Sounds like a fun winter project, if your garage is heated :B
