I have been tossing around the idea of installing a rock-crawler type bumper on the rear of my 73 with a tire carrier that also has places for jerry can holders and a hi-lift jack. A potential problem I see is the location of the tail lights. The round ones are mounted below the gas filler, just above the rear crossmember. They look to be about in the location of where the tire carrier pivot mount and the latch are located. Has anyone mounted one of these type bumpers without modifying the tail lights? I don't really want to redo the body. Thanks.
