I am currently looking for some replacement parts for my L-2000 tribute but I can't seem to find them anywhere, partly because I don't really know what to look for:
The first one is a 0-shaped ring (washer?) that used to be part of the tuner. It used to be sitting in that hole:

The part itself looks like this:

Would anyone happen to know where I can get one of these?
The second thing that I'm looking for is a pot, one of mine seems to have reached the end of its life span. The G&L website has them listed as "POT - TRIBUTE SERIES - LONG SHAFT" and mentions three types, 250k, 500k, and 1Meg. Unfortunately the 1Meg (which is the one I am looking for) seems to be unavailable. Are there any known "drop-in" replacement pots? It seems there have been other people trying to find suitable replacement parts but I could not find anything that looks like it would fit.
While the first issue is mostly just cosmetic, getting a working replacement pot would be great.
