So I found out I have the 26 spline with 29 teeth gear which is 2.97 vs the 31 which is 2.66.
I also noticed a few shims were used to eliminate end play.
Since I have no use for the 26 spline 31 teeth I'm selling it for $270 shipped if anyone is interested.
Can someone please give me a little more info on how to install the 26spline inoutnshaft ? Everything is off and when I install the shaft the cover doesn't want to close thanks !
