Gears & Axles - U joints - Strange 12 bolt

I have a strange 12 bolt with all options.. traction control, abs, 33 spline axles, updated posi, ta girdle, etc, etc. I know they have heavy duty u joints to match the rearend. I have the updated yolk. I looked on stranges website, but none of them rang a bell. If somebody has a parts # or a link, it'd be greatly appreciated as this is my daily driver.. and I have nothing to go back in there as one of the caps fell off.

The crossover U-joint (1310 to 1350) that comes with the Strange rear is a Spicer #447 - you should be able to get one at your local Napa.
