A perfect match!

I've heard of defrost motors being swapped in for a heater motor with a few mods.
Beautiful work BTW

Edit REAR defrost motors
the heads are indy 572-13,s. I'm pretty tight to the firewall. I only have about 1 3/4" from the valve cover and the blower motor. I haven't figured that out yet....

it is true, I have the most room on this car, than on any of my chargers or cudas!
