The problem with using thin tire material is that there's no lateral support where the rivets go thru the holes in the support. The liquid stuff fills that space between the rivets and the holes and keeps it centered, but allows some cushioned movement. I made sure that the rivets were centered in the holes so the part that bolts to the tranny is supported both laterally and front-to back. With tire material stuffed in between the plates, it can slide around.
