under dash a/c units, anyone have pics?

[NEWFISHER]

I'm getting ready to install the engine side of things,compressor, condensor ,dryer etc and am wanting to add an older a/c stand alone unit under the dash. Jdosher on Maggies build used a heat/ a/c combo unit and deleted the factory heater. It looks cool, but I HAVE to retain the defrost here in the NW. Anyone add an underdash unit like the Mark IV from Vintage Air or an old Sears unit and have some pics? Wondering what models will fit in the center and still keep the OE heater defroster.
