63 Fleetside rear bumper

[Harris 63]

All,
Good afternoon just have a quick question about a rear 63 bumper kit. I recently purchase a bumper kit from Brothers for some reason the brackets are off an inch have anyone ran into a problem like this before?

Are you talking about width after brackets on frame, or holes to bumper to brackets....you may have to message them on the width, frame tolerances tend to make a difference, plus you really don`t know what the truck has been through after 50 years...
