thinking about ways to heat a conquest.. anyone ever tried putting a heater core on the return rad line and hooking up a small fan with ducting to heat the passenger compartment?? was just looking around here tonite on the princess auto webpage and couldnt find and heater cores.. if anyone knows where to buy and how much could ya point me in the right direction. i cant see a small care being anymore than 150 bucks and fan and ducting would probably run about 70 thanks
