Take your bearing samples to any local bearing supply.  Ampico and
Duo-Art crankshaft bearings are a standard item.  Duo-Art rod bearings
are something else.  McMaster-Carr is a good source for bearings,
as well.

I'm having heart surgery on Monday, so those of you who've requested
Ampico B brake drums will need to wait a bit more.

Thanks,
