I wish I could be more help to you but you might also try posting over in the "Drive Train" section. Couple guys over there build diffs for a living and could tell you in a second. But my unexperienced opinion is no, you can't. Hope I'm wrong.

I bought a 1350 pinion billet yoke from Tom's. It's been machined on a computer controlled machine. It' a little bigger in diameter than stock. (3/8 inch bigger in diameter?) Looks beautiful.

My Richmond 5 speed has a 1350 yoke, which is also bigger than stock. So I'll be looking for a custom made driveshaft.

The stock driveshaft is built for 1310 u-joints. To make the Richmond mate to a stock driveshaft, you need a 1350/1310 adapter U joint trunnion. Since I bought a 1350 pinion yoke, I'll just go for a custom made driveshaft.

Factoid: the 1350/1310 adapter u joint trunnion, was stock for the Ford Edsel.
