How to swap the knob and bezel from OEM lightswitch for AAW

[msg]

The American Autowire kit has the lightswitch with a chrome knob on it that I would rather use the OEM knob. Is there a way to do this? I didnt want to break anything. I did remove the shaft from each by pressing the side button, but the AAW shaft is taller and I didnt know if trying to jam in the OEM knob and shaft to the AAW works or not, or if you have to remove the Knob and place it on the AAW shaft.
