I would assume that the v6 case is a 23 spline?? I know that my 4cyl stuff is all 21.

Check out this thread for the install, it may help a little
http://board.marlincrawler.com/index.php?topic=23424.0 Ok I have my flame suit on. This may sound stupid, but if I want to upgrade my gear box to a 23 spline setup what do I need to do to the tranny?
Thanks!

I'm not really sure. I didn't have to do anything with my tranny, but then again, I've got the r150, the 6cyl tranny, so it is already designed for a 23spline input
