12 bolt problem with torque arm I talked to the mechanic who is installing my rear end today, and he said, "the bolt holes for the torque arm on the 12 bolt are staggered and the torque bar won't fit because it goes straight back?"
Anyone know what he is talking about? He's going to call Moser Monday, but I was wondering if any of you ran into this.

Some people have to do some grinding to the torque arm a little to get it to fit properly. Also make sure the mechanic is not using the factory bolts. Moser 12 bolts take 4 smaller bolts which should have been supplied with the 12 bolt.

Well the mechanic described it as coming from the front of the car along the driveshaft so maybe he meant the torsion bar?
Maybe the stock one was taken out because there was a custom 8.8 rear in the car when I bought it.

The strange 12bolt rears dont require modification to the torque arms usually. Its the mosers that need to be messed with. My strange 12bolt fit the stock and aftermarket torque arms just fine.
Seems like you have a moser...since your mechinic was calling them. What the other guys said about needing to use the different set of holes is accurate. What kind of torque arm are you using?

I don't think the problem is with the torque arm now because that apparently isn't the problem.
Okay these people can NOT get the name of this part correct so I'll describe what they said.
"It is a rail that runs along the driveshaft from the transmission and bolts to the rear end."

Thats the torque arm.... Not a torsion bar. A torque arm, simply put, controls the rotation of the pumpkin due to torque. A torsion bar is a bar that is usually twisted or preloaded and takes the place of coil springs on independent suspension set ups.
The only part that runs from the trans to the rear on an f-body, besides the driveshaft, is the torque arm. Unless you car has some aftermarket parts that are usually found on our cars. Cant imagine what it would be though.
Your mechanic SHOULDNT have much issue getting around the fitment issue. Most of the parts should work together. However...Moser rears usually have different parts for things like torque arms, lower control arm relocation brackets, and a few other things. For instance, on Spohn's website, he sometimes will say order part number xxxx for 10 bolt and strange 12 bolt, and yyyy for moser 12 bolt.

EDIT: Well the post above mine sure clears it up!! haha. That would present a bit of an issue!
