Driveshaft loop location.
That's the problem with this universal one.
I have shortened the upright on the L bracket. The hoop part rests against the tunnel and the brackets are around 3/4" from the floor. I'm not sure I can bend the 1/4" thick steel. Will have to bend the 90deg bend tighter to like 45deg, then put a bend back down so it will hit the floor properly.
