I bought a 1350 u-joint to replace the front joint in the front shaft, because thats what the rear shaft used, but in fact, the u-joint is a 1310. Wtf is that? So I assume I need a NAPA conversion joint to connect my stock 3/4 ton shaft to my D60. What is the part # for the covnersion joint? Thx

All GM front axles (10 bolt, Dana 44 & Dana 60) used the 1310 joint for the pinion yoke. Unless someone swaps out the pinion yoke or driveshaft a 1310 is all you need to connect it.
 
Yep, all lower fronts are 1310s on GMs. But it's really not as FUBAR as it seems because the 1310 is pretty much always straight (due to CV on top) in anything close to stock configuration. The only time it gets far out of straight is when longer travel suspension or excessive lift (without corrective measures) come into play. As long as it stays close to straight, the 1310 can handle quite a load and is rarely the week point even in 1 ton duties.
 
then buy a couple of 1350 yokes, one slip and one pinion
