I need a couple of busted winches for the Harken "trade-in" program.

Don't know about Seattle but down here we have "Yacht Surplus"
junkyards (Minney's, for example) that usually have a few seriously
busted winches available. You'll pay more than ten bucks for one just
for the scrap metal (aluminum or bronze) value, though. And even the
seriously busted ones have a gear or two in them worth more than ten
bucks.

I think you're dreamin'.
