I have been rebuilding MoPar switches for over 20 years.
ALL of my switches carry a lifetime warranty.
These are all factory switches, not the 'offshore' junk.
All C body EXCEPT Imperial
Thumbwheel Dimmer Switch $135 (68-71)
Headlight Switch (1967 Chrysler, with wiring) Currently Out (68 and later will work)
Headlight Switch ( 67-68, without wiring) $125
I can also rebuild just about any of your original switches, including the power window switches (all years, inquire)...
Rebuilt 67-68 Dash Switches Headlight / Dimmer etc
