Pretzelized 8.75 housing

Back in the 80's my friend had a 440-6 727 coronet R/T and he put solid motor mounts in it, so he had to test then out so with the hood on the roof he brake torqued it to about 2500 RPM then it had a bad vibration, so bad you couldn't go
15 MPH. Found the pinion pointing at the floor so we thought it broke the welds on the perch's. Not so it twisted the tubes on the housing, I couldn't believe it was possible to make that much torque to twist it but it did. I have no doubt you bend and twisted it up, I would go with a Dana 60, I have done a lot of them and never seen any one bend one, all you need special is one billet cap for the left side and you can abuse it all you want.
