So I may have found the rear end. I just want to confirm, as the cab and bed is not original. He told me that he bought it complete and was unable to get a title and scrapped the rest. It was a '72 3/4 ton, Cheyenne special, with a big block v8 and th400. He indicated it was all original. It has the round domed pumpkin just like my '49, and a coil spring rear end. Its half buried in the dirt, but I counted 10 bolts.
I guess before I lay down the cash for it I want to confirm with those who know much better than I whether or not it is the 4.10:1 that I seek. Link below to the photo of the picture:
