I've got a friend piecing together a drivetrain for his 65, thinks he's missing a plate that goes between the motor and trans. I've seen these for 360s before, does anybody know if there was such a thing for the 327 or if it's required?

The J-Series parts manual here http://oljeep.com/edge_parts_man.html should tell you. Let me know if you have trouble navigating or interpreting the book.

Thanks, I forgot all about that.
