The factory torque arm bushing that bolts to the tranny is different from the a4 to m6. The crossmembers are different too. One thing that i did when i did my conversion, is i bought a torque arm relocation kit. that just makes it easier.
BMRs torque arm relocation cross member is an awesome piece of work. Just installed one on my car a few weeks back. They're about $250 and worth every penny.
