1 Row Heater Core

[BAGN]

I was told a board member used to make the 1 row heater coers for ATR. Does anybody know who that was. I want to keep my A/C & Heater when I put my STAGE II in. I got the panel that ATR sells (to give you a little extra room to clear the Stage II valve covers) but they no longer sell the 1 row heater core. DOES ANYBODY KNOW WHERE I CAN GET ONE?

Thanks in advance
