I'm pretty sure the spline count and diameter of the pinion is different from 12 bolt to 10 bolt. So you will have to get a new 1310 or 1350 yoke. Those are already set up for a 1310 or 1350 u-joint with tabs. (You can specify which one you want). If you have a reputable driveline shop nearby, ask if they have a conversion u-joint that will connect your shaft to the 10-bolt yoke. I know they make them for going from a 1310 to a 1350, etc, but those are both external ring type. But in reality, I think that getting the yoke is the best bet IMO.
