I've dealt with
Kellogg Automotive - Water Pump Rebuilding - Water Pump Parts - Obsolete Parts Manufacture for parts to rebuild a water pump on a John Deere engine.
Their story is they bought up closing water pump rebuilders and started in the business.
Mom answers the phone and probably packs the stuff out for shipment too.
If you google map them, there is a dirt race track not far away from them.
