Ken, how do you know that he has the same rear end? Your post #8 has a great big IF in there that Milkdud hasn't addressed. The vehicle is 56 years old and could have had just about anything put under it at this point, unless I missed something. All he said is

Mainly because one of the rear ends was from a 63 while another was from a 64. There a lot of differences between a 62 and 63,4,5 and 6. The 62 has a wrap around windshield and a small back window and the 62 was the last of the torsion bar front suspension. The rear ends were, for all practical purposes, the same until 65 or 66 when they went to 5 lug.

So how do you know he's got a stock rear end? From what I've read he could have a DANA 60 or a Ford 9 or something out of a later model Chevy truck, right? All we know is 6 lug, 3.73 ratio and he's happy with it. Maybe I missed something? Help me understand.

I still think Post #9 is key to understanding.

In his first post he says he has to stick with 6 lug wheels, Do any of the rear ends you mentioned come with 6 lug?
I was merely relating my first hand experience, I tore one up backing out of a gravel driveway a little too rapidly. And until the OP tells us what he has this whole deal is an exercise in futility.
