Can’t remember what part of the Power Wagon shaft broke, but know it was more than just a U joint, as I could have fixed that myself. As I recall it cost me more than a hundred bucks to have fixed at a drive shaft shop, which back in the 70’s was about a weeks pay, ouch!
Unfortunately the large yolk outputs of both the transfer and trans have the drive for the speedometer cable, so aren’t interchangeable with the input. What I was hoping for was a 1350 yolk that would fit in place of the 1310 input, but maybe such a thing doesn’t exist. Of course the stub shaft would have to be custom made, but I have a spare that could be modified.
Thanks for the reply

Well I guess I was totally wrong (go figure). I dug through my box of spare 221 parts and it turns out all the input and output yolks are interchangeable. Unfortunately all I have is a pile of 1/2 ton 1310 yolks. If anyone out there has a 3/4 ton case that they’d like to run in a 1/2 ton I’ll gladly swap outputs with you.
Also found out the 1350 output on a SM420 is definitely different. That’s the one that has the integrated speedo drive gear. Had them mixed up.
So anyway, I guess I’m finally figuring this thing out. Once I find another yolk I can have one of my spare shafts modified. Goes to show you really can’t have too many spare parts when you’re into this old junk!
