I read through quickly (have to get to work), what's everyone doing for heat? I'm thinking that I'll build a heater box under the left rear seat and put an inline thermostat on the hot side of the system just after the input for the heater core. My car has a duct running down each side of the car. I assumed that one was fresh air into the stock heater manifolds and the other was hot air back into the car. Am I right?
Thanks.
