How many different U-bolt pinion yokes?

Hello all, I'm working on a 8 3/4 rearend with a 741 case. Removing the open 2.76 and adding 3.23 w/truetrac. The yoke being removed was 29 spline and the 3.23 gears need a 10 spline. I'm trying to determine how many options are feasible; what I mean is this, what appears to be out there are the 7290 or 1350 U-bolt Pinion yokes. Am I missing any or are these the only 2 sizes out there?
