Re: 1972 GMC 3/4 ton rear axle ????
You`d know a Dana70 from a D60 if you saw one.That would be a way big rear.Like comparing a D44 front to a D60 front.The D60 came in the lower 4.10 and 4.56 as well.You hear alot about the 3.54 because it`s unusual for back then and great for today`s needs.Was that a big block originally?I saw the pics you sent,nice truck for the money,and noticed a later small block was dropped in and it has alot of options.The 1/2t big blocks trucks with automatics only came with 3.08s.I`d assume a big block/auto 3/4t would only come w/3.54.
You`ll find a "60",as mentioned,on the lower web in the center section.
