I looked at those a little while back... problem is not only are they not listed for my 1996 Ranger, but they also are charging ridiculously high prices for so called 'brush guards' when they are in fact quite flimsy in both construction and looks, IMHO. I bet hitting a small (6" or bigger) tree with either of those headlight protection bars will still result in a broken headlight.
So I'm building my own. 2.5" square tube, 1/4" plate, and a couple other pieces of steel. It'll be fairly light weight, but much stronger than the ones you posted the links to... I want to be able to run over small trees, Smart cars, and Priuses.
Plus for where I'm getting my steel, I'll be into the whole bumper and winch set up for around 500 bucks. KC Daylighters will add about 160 more onto that figure. So for the price of one of those brush guards, I'll have my truck all decked out and ready to rock.
