Regarding the standard dash fader knob. The standard dash bezel I bought at Carlisle this year had a single pot fader switch already on it. The knob looks to be the same as the Rallye knob. Based on the info supplied by poster Burdar on his replacement kit I purchased a Rallye fader switch and am going to try and swap over the standard dash knob and bezel. The ones I have on the bezel I bought are not in great shape so I will look into getting better ones though.
