u1645 conversion u-joint
But for my Moser 12 bolt, i had to install a new u joint on the *** end of my drive shaft to fit the bigger yoke on the Moser 12 bolt,,the stock one would have been to small (the end caps that you put the U or C clamps around and bolt to your rear end yoke)
here is what i used,,,,,,post number 7 i think...

to remove your stocker, you will need to "melt" the nylon that is in the endcaps out, remove by hammering down on the end caps that were attached to your rear end yoke,,,this will lower the u joint out of that end cap,,,flip it over and do the same thing to the other side. Once the u joint is free, remove, and install your new one with either a press, or a bench vise. Be sure to grease it up good.
DO NOT HAMMER ON YOUR NEW END CAPS TO PUT THEM ON!!! You will spill your needle bearings all over the freakin place. (ask me how i know that one)

once again, not sure if this applies to your situation or not.
Good luck and have fun.
Another case cracked.
