Would welcome pics of your door jamb switches, preferably showing the size wrench that fits it, and some info about the vehicle. I am in a bit of an argument with Rock Auto over some switches they are advertizing and I bought. Their listing is advertizing as fitting, but actually does not fit, a 75 Sport, so they claim someone either altered the vehicle or it's a one-off. But the original switches from the Sport take a 9/16" wrench to remove. The ones they are selling use a 7/16" wrench, and the threads are about 1/8" smaller than the originals. I have removed many of these switches from other year A bodies and they are all the same size - 9/16". But with Mopar I've learned to never say never. I have seen this size switches on an E body but not an A body.
