Yep, it's not there and there is space for it. Only way it went missing on my watch is if it popped out while driving the old bearing out, and hit the floor, but I swept up no such beast. I wonder if the PO had it apart and lost it. And I did not realize, because it was not there? Oh well doesn't matter now......damage control, now I need an 18" spoked wheel and the missing spacer as well.
Any helpers out there would be greatly appreciated !!
