Rod Clearance Issues (new)

My guess is that the added material from the rod thickness is messing with your clearances and my vote would be to modify yours or make new ones with your current shifter, if you like the super shifter and you are up to the task.

Quite honestly, pntastar69's suggestion of watching the gear movement is going to be the best way to determine where the clearance issue is.

You have already determined that it's an issue of fitment to the chassis and not within itself. Look for bind in whichever gear you are seeing a problem in, mark where it hits the rod, remove it, bend it accordingly, readjust the rod length with neutral locked out and you're golden.
