Thanks Bill -
I called NOS part in Texas - they are sold out.
I also called Collectors in WA. and they are sold out but offer a rebuild service. Cost is $220 plus a $50 core charge.
This is good to know in case anyone needs to re-hab a 226 water pump.
Slowly reassembling a basket case 1951 F2 pickup. Take a look at my album in my profile to see how it's coming along.
