Another Mopar Off My Bucket List - Barracuda Fastback

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...
there used to be a guy up there in cornhusker land that sold those in alum., on the internet, along w/ alum. heads and stuff. I bought a set of alum. heads and valve train off him. the heads are pretty decent, w/ a few parts changed. the rockerarms were bad upon arrival, and he wouldn`t stand behind them !
