Funny you should mention Jeff - I wrote him earlier this evening and he replied back already with the part number and description for a brushplate bearing, 622-216. It's .001" over the diameter of my armatures, so it looks like an excellent fit and a longer lasting solution, assuming I install it correctly! I like simple!!!
