The top ones or ones that go through the bumper and tie into your frame mounts . Check out groundponderfab on eBay he sells some 4" ones but if you message him you can get them longer I got mine form him they were 1"x2" -12" long I see he does not have any listed right now but just message Eddie and he will hook you up I have had him custom cut me a few things in the past and he sells his cut parts almost as cheep as the steal cost lol Jeep and Offroad items in Ground Pounder Fab store on eBay!
Like the look of your bumper a lot ! I wish our frames were not so low I hate how far down I had to make mine in the center to hide the frame but I like the way you made the sides slimmer than I did it looks good that's kind of what I wanted to do but just could not work it out when I was making my templates
I went with the squared off mounts, I think they fit the truck and bumper well as both are boxy, and I thought they looked nice and beefy.
mine are positioned so that they mount flush with the rear side of the bumper and butt up against and are welded to the 1/4 plate mount that bolts to the frame
where the original tow hooks were bolted in (I was actually able to re-use the tow hook bolts as well). so when you pull on them you are pulling on frame, not bumper.
mine is plasti-dipped for now, I will get it rhino lined as soon as I get a rear one built.
I sanded mine down, (you have to sand alot and get all that chrome off,) then used adhesion promoter and rattle canned it, after a couple of months I have small pecks showing up, my plan now is to plasti-dip it followed by several coats of paint to give it the right color and a shine, I done that to my front and back bumper originally and it turned out great. the plasti-dip adheres very well to a slick surface and should have a bit of flex to it.
What kind of paint did you use? Would have never guessed it was rattle canned. I had my grill plasti dipped for a while, after i ran my truck through the mud the plasti dip never looked the same even after cleaning it a few times so I peeled it off.
