Here are the original directions from my ‘53 GMC NOS heater, thought I had them as a PDF but cannot find it.

There are several switch options, originals are pricey and look like this. They mount in holes provided on the left side of the dash as shown. The defrost knob is for an Air-Flow but switch mounts in the same location (it says Heat).

This is all the hardware with correct switch for your truck.

Ducts and splitter with rings.

Hoses, notice the sizing thus the fit rings.

Finally the block-off plates for the cowl louvers and firewall.
