Harrison Heater Knob

thingiverse

The Harrison Heater Knobs were designed specifically for use on 1941 Chevrolet trucks. To assemble these knobs, you will need to access the rear of the assembly area. First, locate the knob halves and ensure they are properly aligned before applying a suitable adhesive, such as epoxy or super glue, to bond them together securely. Alternatively, you can attach one complete piece from the back by using a screwdriver to drive a screw into place.
