'72 GMC 4wd rear bumper brackets
 

I have a '72 gmc 1/2 ton, 4wd, longbed and I bought a regular rear bumper for it, NOT a step bumper. Does anyone know about brackets for these? I talked to the tech at brothers and he said that the brackets for a shortbed 4wd would work, all I would have to do would be to re-drill some holes. I just didn't know if I should buy those or fab up my own.

Thanks
