Todd, I think it goes in the center support but I don't see it in the illustration you posted or in my book. thks btw. It has eight small teeth on the innner diameter and eight waves and is .042" thick.
Chris to the rescue again! Thanks, took out clutches and installed wave plate on top of the piston. Reinstalled clutches, plate and snap ring. Got about 045" clearance now. I see it now in the manual. the manual shows one that has 2 teeth on the outside diameter and appears to be dished. Must be different designs. this is a 96 model. mmm, don't know how that other pic got in there. Thanks again.
