Make your own... tube steel and cut the tabs/brackets off the original torque arm for bolt alignment.

its unibody.. their might be something to bolt to but defiantly not the chassis.

Re: need help with rear torque arm

A direct chassis connection is the last thing youd want. In addition to rotating, the TA has front/rear travel. Youd rip out the bolt in the trans tunnel even under light driving

The simplest solution is to take the old bracket from your 700R4 or T5 and weld an angled piece the the bottom, then bolt the angle onto your TH350 crossmember

Re: need help with rear torque arm

there is a bracket that you can purchase I think from edelbrook that bolt to the back of your tranny. I picked one up from craigs list for 50 bucks used in good shape.Can send you pics of it if you want to use that as a basis for your fabrication. I may be parting with it if I decide to a different rear suspension setup.
