Denny;
I went to a place called Machine Services here in the Green bay area. They deal in drive shafts, u-joints, king pins and a lot of other stuff. The number is 920-339-3000. I just took my drive shafts in and they came back squared away.
Just looked at my 46-72 parts book, looks like most of what you need may be common to all 3/4 and 1 tons up into the 60's.
