Finally got the aftermarket heater CV installed. The factory one was leaking. The old CV is still in the car, attached to the firewall. The new one is just zip tied into place, and I don't have the temp cable attached because it won't reach. Not sure if I will run a new cable, or eventually just get the old CV rebuilt. For now I've just left the valve wide open, and let me tell you, the heater will cook you out! I've been picking up my daughter from the school play practice at 10pm the last few nights, and its been 40 degrees or less and windy to boot. It was so toasty in the car I had to shut the heater fan off and crack a window.
Here's a shot in the garage after I drained the antifreeze out of the radiator. The pic in the driveway was after I took a short test drive to fully warm up the car; wanted to make sure there were no leaks. I will drive the car until it snows no matter how cold it gets.
I really like driving the car at night, and especially when its chilly. It just ads to the experience. I talked to a guy that is part of the pit band for my daughter's play (after play practice was over); he had to walk by my car in order to get to his car. He graduated in 1975 and has owned a 67 Mustang since then. He liked my car a lot and we had a 15 minute conversation about it. It was fun even though it was dark, cold, and windy!
