You did a great job with your bumper. i just picked up on this thread, so if anyone is following along and liking what was done here I have a few ideas to toss about and get you thinking...
I got friendly with a local shop (read as "spend money there"), and the guy let me use his tubing bender. A case of beer or green in his pocket would do the trick too.. then I would take the long pieces home and cope them to my liking -
But FIRST - I reinforced the snot out of the stock frame horns - I felt those were too spindly for the torque and leverage that it would see.
To start the bumper, I welded the end of a short piece of tube closed, drilled a hole in the center and then bolted it to the front of the frame horn. That gave me a 3" tube sticking straight forward from which I could build.
I left the winch off, and just put in a reciever so I could put the winch on the back, on another truck, wherever.
In order to get the maximum possible approach angle, and keep the reciever as low and back as possible (to decrease leverage) I made the front tube center section removable to clearance the winch when it is mounted.
To keep the Aux lights as far back and protected as possible, I cut some vertical slats out of the grille (three per side) and set the lights flush to the front of the grill - even my deep, ballast integrated HIDs fit there cleanly.
Looks like you were able to keep the radiator skid, but since I went with a SAS, my radiator was very vulnerable so I had to make an extention for a skid - the local shop also has dimple dies, and I have a press, so.....the skid got swiss cheese'd and dimpled, and mike's pocket got $10 fatter.
Some mounting tabs and aluminum panels will hide all the ugly back there and offer better air flow around the bumper as well.
I also think that headlight hoops and a stinger of sorts is a good idea - seeing as how we live where the deer and the elk-a-lope play. I made the hieght of mine just enough so that I could see the top of the tube from the drivers seat. This I find handy for tight manuvers, yet does not encroach upon visiblity.
Anyway, there's my 2 cents - hope someone finds it helpful.
