If the enclosed drive shaft on the big bolts are anything like my mini-3/4 ton, you may want to check the length of the drive shaft. Mine has a extra set of universal joints and an additional shaft for the additional 13" of length over the 1/2 ton.

Of course my truck is "modern" compared to yours, but "ancient" compared to a 57 drive shaft and tranny.


If it ain't broke, take it apart and figure out why!
