Just saw your offer (I'm a year late in responding!) I was able to get the dimensions and made replacement pins, I also have acquired several heater controls 67, 68-71 A body and 68-72,3or4? Truck of all things. I have a design for the sliders but I might modify the OEMs design to prevent the little spring tabs from breaking off, basically make it more robust. Another member is going to test my current design for me in real world conditions.
