I had this same issue with my 57 and used salvaged washers as well. Has anyone investigated using a flat washer, or a punch out from an electrician's punch
Post is edited. Just looked at Amazon and a punch like I was thinking of won't work because the ID will probably be too big as these punches require a draw bar to pull the dies together.
Any one have a heavy duty shim stock or sheet metal punch to experiment with?

Reason: electrician's punch won't work!
