Bumper Mounts
 

Getting caught up on some things and I have bought material for some bumpers. Im wondering about the mounts and things associated with them. I see bumpers advertised that have 4 bolt holes for mounts. I read on here a different story tho. First off, what is meant by Uni-Body tie in? Also what is tue purpose of a steering box spacer? Is this an upgrade to a factory spacer? Mine looks like it may have something behind steering box but it looks like cast aluminum. Not beefy at all. Ive made enough mistakes with this project and Im hoping this will go smooth.

Once again. I shoulda searched more. Got it.
