Anyone have a source for a replacement generator pulley? I accidentally broke mine (there isnt much too it, looks like pot metal) and need a replacement. 1950 Original 6V
Thanks!

For anyone whos interested, I picked up a cleveland 300 die cast pulley at tractor supply for 10 dollars. I had to ream the bore a bit and grind on side of the hub, but it works like a charm.
