Not sure if this will help, but my car too has power steering and it's a four speed.
I had to add a 1/8 inch shim under both motor mounts, and tilted the motor ever so slightly a couple of degrees on the mounts.
not an option
you have a 72, which means biscuit mounts, those are shimable
he has a 73, which means spool mounts, which to the best of my knowledge are not shimable
(on my 71 duster, I had to shim the passenger side mount to clear my dougs headers)
