On the trademark USD horseshoe which holds the the black disc seat there appears to be a rubber (possibly and old oring) on the stem in between the seat and the back of the seat holder. Wish I could picture this one to you all. A. Is this an oring, B. Is it just verdigree, C. If an oring is it replacable? D. How the heck do you replace it.
I originally thought it to be dirt and goo but now have found it to be an old oring or some type of a rubber spacer for the seat mechanism to buffer itself on? Any suggestions or is there a manual from Bryan I can get.
