Bed help 55-59 and 60-66

[1project2many]

I have experience putting a '62 long stepside bed on my '57. I had to move the fender mounting holes forward and and drill a few new holes for the '57 steps. The '62 fenders appeared the same although I used the '57 fenders because 1) I'd already done the work to repair them, and 2) the '57 has a bed mounted spare. I seem to remember having to change crossmembers under the bed but it's been years since I did the swap. The GM parts book showed the same bed sides, front panel, and tailgate could be used from '55 to the last stepside in about '86 or '87 so I used a new GM tailgate and chain when the truck was restored in '97 or so.
