I had the Spohn setup on my car. It was the trans crossmember and crossmember mounted torque arm for the TH350. I'm building a new crossmember for the T56 thats going in now. I realized that to have the torque arm mount in the same place as with the Spohn crossmember is not possible while having a double hump crossmember for exhaust clearance. So I was going to make a mount out of box tubing going from one subframe connector to the other subframe connector and attach the torque arm this way. This plan is not set in stone as of now though. I did some quick lining up and it looks like I will still have room for my exhaust the way I want to run it. The exhaust would actually sit above this bar. But I need to do some more precise measuring to make sure I can get the pinion angle I want with the bar here.

My main question though is compared to the length of the torque arm as it comes from Spohn, how will the car feel if I cut about 5" out of the arm? I was going to cut the 5" or so out of the back. I was just going to buy new tubing adapters and weld them in.
