So question you guys, do I need to measure the step height on my FW to gauge how much I should shim the pball? or is there another way to determine whether or not I should shim (while the tranny is off - keep that in mind lol)

I've read through this; http://teamrip.com/when_why_and_how_to_shim_pivot_ball_info.html

and many other posts on why/how to's..

I'm starting my re-assembly tomorrow and would like to figure this out before.

Thanks in advance!
