I finally got the 6L80e back from the guy that changed it over to 2wd. When I did my measurements against the 4L60, the mounting pad was only 1 3/8" further back. No big deal, drilled my holes for the PB crossmember in the 4 spd and 6spd positions and went about using the 4l60 as a placeholder. When it came time to install the 6 spd I realized that the crossmember would need to be flipped with the pad towards the front vs towards the rear as with the 4L60. That little move put the crossmember into my mufflers, so it wouldn't work without further modification if at all.
I carved up a piece of 2X4 11 gauge tube and made my own crossmember to support the 6spd and clear the pan and exhaust. Good times!
