Would like to know What vehicles still out there that are all mechanical. No solenoids, no electronic anything. Seems like I am always tracking down and replacing these POS gadgets that leave U stranded. Would like a simple fuse box and nothing else! Most likely looking at something pre 1975 I am guessing. Someone told me the Cummins 12 valve would be a candidate. Anything else? How about the square bodied Chevys? How about something smaller? Any cars?
