Fits both the Long Bed and the Short Bed
The main difference between the long bed and the short bed are the holes used on the mounting plates. The hitch receiver was designed to sit behind the fold-up license plate without interfering with the spare tire underneath, with up to a 31in tire fitting under the short bed, and a 33in tire under the long bed.
Getting Started
I removed the old bumper first and started with the hitch so that I could build the new bumper around that.
The hitch mounts were cut off so that I could mount it much higher and a little further back, to provide better departure angles. I also sanded and painted it with a Rust-oleum Clean Metal Primer spray can, to help prevent more rust.
PLEASE NOTE: there are warnings to not cut or weld the hitch, so doing any of this is at your risk and you should fully understand what could go wrong if you do not weld and assemble this properly!
