Yes I searched and I cant find the #

What is the part number for the rear u-joint to go from 10 bolt to 14 bolt?
I need a spare and for the life of me find the part #.

I think you're looking for a conversion joint. Here's what I found:

Also if you just go to Napa they should be able to dig it up just by telling them what you're trying to accomplish.

It can be either a 447 or 448 depending on if you have a 1310 or S3 joint on the 10B. Measure the cross and cap and compare to the joint at the store.

most 10 bolts use an s44 joint which requires the #447.

If you have a 12 bolt or someone swapped in a yoke and driveshaft for the 1310 you will need a #348.

Are you using your stock drive shaft? I took the heavier shaft from my donor truck and had to measure the caps to get the correct one.
