I need to replace my heater core. I have a 53 Chev. 3100 with a heater like this

Has anyone purchased one new for this heater and, if so, where. Some of the suppliers I have tried show the core in their catalog but are out of stock.

According to Dads50[whose photo this is, Thanks]it is a H-02-47 heater.
