you should have welded the tcase cross member to plate and then to the frame, or at least gusset it. I doubt you would like it to bend or rip a hole in your frame
I am reattaching it to the frame on 1/4" angle iron and adding gussets to the top and bottom of the tubes this weekend thats already on my list... I gotta pull the tranny and t-cases anyway....thanks though bro
