IF, all is still stock, after removing the lens, their should be two small screws that holds the bulb socket to the housing. Remove those screws and the socket will pull out from the front.If when it was re-wired, it would have a new lead from the junction blocks down behind the grill and into the bulb holder/socket. It required the new wire to insert into the socket from the rear and a new contact to be soldered on. If not careful in doing this the contact/wire could touch the housing causing a short. As mentioned above, removing the baffle in front of the radiator to feed the wires in and out to the junction is the easiest.
