TTI headers hit torsion bar on drivers side???

Would shimming the trans mount help? You'd have to double-check the pinion angle before & after. Isn't there a little wiggle room with spool mounts when dropping the engine & mounts into the frame if you tilt it slightly? Kind of "encourage" it with a bar before putting all the weight down. I also leave the mounts loose at the block ears until it's fully saddled.
