Heater box removal question

formula_s said
The heater blower motor is for an A/C setup. Is that the way you want to go or revert to a non A/C setup?

Thanks for the quick reply. I want to go heater only. I forgot to mention that I got the inner 1/2 of the box and heater core removed. I could tell that it was a mismatch of parts. I will probably be replacing the entire assembly with a heater only box, if I can get the old one out. What concerns me most is the lack of 4 holes for the correct blower. Is an adapter plate available?
