When I take off the rear dual that is in need of repair, I will take a look at the wheel and determine the wheel type. Thanks again for your help. I don't have any pictures of the inside, but to the best of my knowledge, the wheel center is revited into the wheel ring and outer sliver portion is the locking ring. I'm a newbie at this, but trying to figure it out. Thanks again for the information. I will post pictures when I get it removed and broken down.
