You would have to move the spring perches though. I had a 78 3/4ton Dana 44 I was going to use but decided not to because the spring perches on it are narrower than the stock Dana 50 TTB. I just decided to hold off till I can find a 60 down the road.
i found a 60 a few years ago but had to take the whole truck to get it for 500 bucks it was worth it! keep looking you may have the same luck!
