Thanks, I've sent off a pic. I'm missing parts 4(both) through 6 of the prior link's diagram. Why would anyone take off the main piece? The other thing that I think is interesting is that the rubber in between the front and rear cover seems to have an inner ring and an outer ring; it's all pretty solid, probably through time and heat. I wonder if the rubber in the middle was the original rubber, and it all just sort of fused together. But why not put the weight back in?

Hmm....
