I just installed a spohn body mount torque arm and I have no idea how to set it up properly. If anyone could point me in the right direction I would appreciate it. Its on a lt1 m6 with a stock 10 bolt.

 

It comes with a level to check the pinion angle. Did you try using that? You want at least 1-deg with a stockish engine, up to 2-deg with higher HP. When measuring the angle of the DS and the angle of the pinion shaft, you need to end up with a "\/" pointing down.

 

I bought it second hand and it did not come with the protractor. I'm going to pick one up now.
thanks

 

You can get a small digital level from Sears for about $29. It's a lot easier to use than the gravity protractor.
