LED headlights with heated lenses, there are at least three Jeep parts/accessory vendors that sell them, they are 7" round lights which plug into standard connections for headlights.
Heated lenses melt snow and ice off the normally cool fronts of LED headlights.
Truck-Lite makes them but they don't sell direct.
It irritates me to need to pretend to own a Jeep to wade through their websites to find them.
+1 on the CD of part numbers, maybe enlist the help of a guy that posts on some of the Ford truck forums by the username NumberDummy, if he doesn't know it Ford didn't make or use it.
+1 on the keyed brake-lock, I remember them, sad to see they are out of production. Either that or I need a Rottweiler
A thicker steel inspection plate for the Dana 20, maybe with counterbored bolt holes.
