My 1951 3100 chevrolet truck has the deluxe fresh air heater in it. The heater control knob (maroon-warmer)twisted off the rod.I purchased a new after market knob and installed it with no luck.The knob doesn't grip the control rod.
I took it back and they can't tell me the proper way of installing it.The tech guys don't have a clue,but they sell tons of them ? I explained that it wasn't any good just for looks,I want to use it.They exchanged it for another new one with no hassle at all.
The control rod has little splines that should press into the knob.Do you fellow bolters know how to install the knob on the control rod ? What is the trick ???
A couple of pictures of the new knob.
