I've got just enough room to put a hole in between the two bolts that attach to the transmission bushing. If I drill large enough I thought I'd weld a tube through it that sticks out far enough to mate with the hoop mount. I should be able to use a 1/2" bolt - at least a 7/16" anyway. I don't think I'd be experiencing any flex except that the thinner sections of the loop mount aren't as strong as I'd hoped. I suppose I could add a lip around the edge that would add strength...
