I had a cold area heater box that had an extra flap that could be opened at feet heat.
( 1975 350 A/T TH350 none A/C unit) 37AMP/43AMP.

If it were a A/C unit it may have had a VAC access climate controls with one or two cables. Those would have the higher amp ALT. as the 66AMP.( might have had a amped up blower)

Or just manual cable only unit with A/C not to common after 80.
Not sure if this will help or not.

I have a cold climate package with no ac on a 78. The heater has always been great and quickly warms up inside. I didn't know about the extra flap at the floor.

How do you open the extra flap? I've always just used the controls in the dash.
