Re: 1959 recirculating heater core - any retrofit options?

I'd love to find another core, from a different vehicle that I could swap in place of my core! I had hooked mine up and it worked for a few months. Then blew a hole through the core and pumped a bunch of coolant into my cab. So now I have bypassed it. Its cold again, so this came up again. I have the rectangular recirculating heater. My core came with one 5/8" tube and one 3/4" tube (for heater valve). If I find a similar sized core that will fit, with both tubes 5/8", 8 can just run the earlier 5/8" valve. Gonna pull the heater core this week and take it to the local radiator shop, but they declined to work on another radiator that I had taken to them, and advised me to just buy a new radiator. So, will be interesting to see if they will even mess with it.
