The bumper jack slots appear to be at a slight angle but due to the spacing difference and the bumper being V shaped it could be an optical illusion....
Of note is the absence of chrome at the lower hole , also the difference in contour of the lower edge of the bumper, possibly a 72/73 model year difference and maybe not OEM Vs Repro difference can anyone confirm this. A friend does have a 72 in his rafters
Anyone who is following this thread notice the box the bumpers are on?
