I have a WC T5 out of a V8 Camaro in my truck and it tilts to the left too
I put a tailshaft housing from an S10 on mine to move the shifter location forward, and the truck tailshaft mounting pad is level and so is the rear mount.
The S10 tail shaft allowed me to use a universal transmission mount which was easy to modify to work in my truck. Not a great shot but here's the crossmember with the T5 truck tail shaft
Here it is again - you can see the universal crossmember adapted to the chassis with some simple square tubing
