Hi Denis,
I'm fairly certain that the '63 used a bumper that had round backup lights,
while the '62 had rectangular backup lights. Our '62s have a "gull-wing"
appearance around the license plate well, whereas the '63 had less curves.

It would be interesing to see if the '63 rear bumper would bolt on to the rear
of a '62. Has anybody tried this????
