Okay, thanks Bartamos. I might just put an idiot light in one of the dash holes that I'm not using (I've got electric choke carbs, so I've got two extra holes to use)
The dimmer switch is designed with a flat mounting pad on the bottom of the switch so that it can be mounted inside the vehicle. I didn't want it standing that proud in the cab, so I bought a couple of spacer bushings and mounted it from the engine compartment side (pics)....now it sits right where I want it and my floor mat fits flat against the floor. I will replace the two thick washers with a single piece of drilled strap steel at some point..
