Thanks JiMerit Boltr#43 and 52Carl. I'm very new with this driveline topic. If I end up getting a rear end from a '60s truck with the correct width do I have to worry about swapping out my transmission because of the gear ratio? I currently have the stock 235 engine and tranny. I assume the gear ratio from a later truck differential will be different than the the 4.56 gear ratio that came stock with my 3600. Also can I use my current drive shaft? Thank you very much for imparting your knowledge on this topic!
