I made mine = bought precut DIY 3"x8"x6' square tube from 4x4iron(no longer in biz) they had a rear bumper kit that you weld up. I made the top swing out carrier on my own, just didn't want to try that long of a cut with my oxy\acc torch
Sorry I didn't take pics as I made it, I only have the first one I posted.
I have seen many many different bumpers made out there so google rear blazer bumper or whatever to get some ideas. If you are not a welder then once you get an idea of what you like see if you can find a local fab shop that can weld something up for you..
