Personally, Worse comes to worse, you can get a heater/blower combo from Summit or the like and install that at a later date. The one I have fits underneith the dash on the passenger side without taking up foot room. Only real drawback is that I only have two outlets, one of which blows up through the defrost vent and the other blowing twards the floor in the middle of the dash. Nothing big but it works fine.
