Hemigmshit 0 Posted May 3, 2020 Hello I am in the proccess of installing a step bumper on my 2013 silverado 2500, but it seems like the 2 holes the allign vertical on the bracket don’t match the holes on the chasis and I did had to do a bit of trimming on the metal because it wouldn’t go in all the way. Im just looking to get tips and some help for my problem.
