The '60-'62 front bumpers are different than '63-'66: they look the same, but the bracket holes don't line up. That's on all of them--trucks, panels, Subs. So find a front bumper from a '63-'66, and it'll work. Rear bumpers are specific to Suburbans, and again, '60-'62 do not interchange with '63-'66. -Brad
That's true, but you can fake it no problem. It's a front bumber that still has the bosses pressed for the front bumper brackets, but the square holes are not punched out when it went on the sub rear. They used different locations for the sub bracket holes.
They were called "Carryall" during that year range. You can use a front bumper for the rear, but you will have to make new holes due to the rear frame being wider than the front.
My mistake--I didn't see that he wanted to put a front bumper on the rear of the truck: I thought he was looking to just replace his front bumper. Mounting holes are not in the same place. The contours might be the same, but the brackets and their locations are different. OR, take your front bumper off, walk around to the rear of the truck and see if it fits. Bullington: GMC used the "Carryall" moniker. "Suburban" goes back to '35 or '36, and is the oldest nameplate in the auto industry. -Brad
