How much space between gas tank and floor? Options

How much space is there between the gas tank and the floor on a 914? Due to the high cost of fuel we are planning on bringing our 914 out of winter hibernation to lessen our dependance on my wife's Blazer. Since the car is liquid cooled I am thinking about using heated air coming from the radiator to heat the car. I want to put a duct running from the front trunk to the interior foot well passing under the fuel tank. Does anyone know how much room there is?

I drove the car 47 miles to work this morning. It was so nice to be back in the car after driving my Civic for the past 3 months. That car is so hooked up. I put heavier springs in the rear since I last drove it too and now it does not bottom out any more. Plus I fixed my broken rear sway bar link and it corners so flat, just like a 914 should. It is nice being able to pass any car any time by nailing the throttle and/or downshifitng. Anyway, on to the heater. It works pretty well if you like having various engine fumes being blown into the cabin. I am going to try some kind of cover to get it to draw clean air from under the car. As it is now the air intake faces right at the engine. I have an oil leak so I smell that and some exhaust. With the driver's window cracked it wasn't bad. The air flow was adequate and the temperature was pretty good with it being about 35 degrees outside. Of course I was probably driving under the influence of carbon monoxide. I can probably come up with some pictures in a few days. Also, I need some help sorting out those heater controls. I can't get 12v at the stock heater fan lead no matter how I switch the controls. I tried swapping the round relays and changing dash fuses. I have a lame Haynes wiring diagram.
