Wrong heat control

Hey guys . . . need some help. My 73 Swinger has the heater controls shown in the first pic. Fender tag sez it was originally an A/C car. The PO butchered the bezel to fit the control (second pic). It has 4 mounting bolts at the firewall. What do I have and what is supposed to be there? I don't want an A/C setup, I am fine with just the heater, all A/C parts are gone anyway. Thanks for any help . . . Rog
