**Which style 1350 U Joint**

Going to have a driveshaft made at some point with 1350 U joints, changing everything over, slip yoke, pinion yoke.

I see there are several different versions of the 1350 U Joint. Greasable, non greasable, and different part numbers for the same greasable or non greasable u joints.

Hope to making 800 to the tires. Which ones do I get?
