I'd consult a casting / welding Guy who has extensive experience in cast iron. A few should still be out there, remember one in Albuquerque 25 years ago, he finally retired and closed up shop. (C J Castings).
Hemmings Motor News shows some possibilities, including one in your backyard:
1. Casting Salvage Technologies, VA 1-(800)-833-8814
2. "Reeve" NY (315)-655-8812 (company name not listed)
3. Fred's Engine Service PA (610)-383-7674
4. J & M Machine, (508)-460-0733 Southborough, MA
5. S & L Motor Service, (570)-342-9718 Scranton, PA
I remember some "Willys" stuff kicking around the local yard here, some time ago, it was flathead, but they crushed out two years ago. The parts were outside of my time frame of knowledge.
