I had this problem before and it broke my tq arm and i went to the hard ware store to grab more bolts but i think they were the same length. Im almost positive. UMI stood behind there product after a few mins of arguing they sent me a new one. And they said that's the problem with the 12bolts are the bolts on the tq arm back out. I'm stick of it now i to the point of welding the tq to the housing.

The problem is the Moser bolts are a smaller diameter than the holes in the TA mounting plates. Moser decided to use four smaller diameter bolts instead of two through bolts like the stock setup and this causes the TA bracket to move around and screw **** up.
One solution is to make sleeves from round stock to take up the slack in the TA bracket holes. There was a guy on here SN Tillery who had pictures but it looks like his album has been deleted.
Some others have just safety wired the bolts or tack welded them to the bracket after they are tight.
Personally I made spacers and plan on tack welding the bolts as well. Good luck,

Larry is correct in his above post.
Moser rear end supplies you with 1/2" holes while the torque arm manufactures like ourselves use 5/8" holes. So first problem is there is too much movement in the bracket that mounts to the rear end. Second the bolts are not deep enough.
The best thing to do is locate some socket head cap screws that are predrilled with safety wire holes, get them at 1-1/2" long thread and a 1/2-13 thread. Locate safety wire and safety wire tool and this will prevent them from backing out. If you have welding ability you can tack weld the bolts to the torque arm bracket.
This is why manufactures don't warranty torque arms with this rear end, it is a common problem.
I hope that helps,
