The bummer about a 1975 AMC DJ-5 postal jeep is sometimes getting new parts. The latest odd ball issue is finding a 4″ wide red stop tail light. I’m hoping Truck-Lite will have a replacement. Grote doesn’t. As I discovered after buying the 40232-5, which has an expansion just before the face of the tail light. Apparently the 4″ wide hole is now an oddball thing. Most tail lights are 4.5 wide.
