Thanks for all your suggestions. I think I will go with what the manual valve under the hood. So if my car was suppose to come with a heater valve that works from inside the car? How would I turn the fan on if I have to pull the knob to open the valve? Just asking, since I would then have to change the heater knob too.
I could be wrong but looking your picture I think your car is a bit earlier than a ‘65—floor mounted starter switch, small speedo cowl, early switch panel and magic wand shifter, so over the years has been modified. No matter, its your car now and unless you’re looking to restore it, shape it your own design. I like the idea that it has a variable speed control for the fan.
