I need a dist part also. the washer that goes inbetween the retaining hub on the shaft and the bottom of the distributor. so if you find anyone parting one out let me know. thnaks

You could form that out of a guitar string or piano wire if you can't find one.

Or substitute an external snap ring (aka "retaining ring"). Easier to source, and easier to remove and install.

Midwest Military has these parts in stock.
