OH, hey, I understand. I usually take mine that still have a factory bumper, set a small countersink, and use a self-tapping screw flush with the outside of the plastic. It's not too noticable. The lower gray section usually comes loose, too, and that gets screwed through, as well, with the screw holding both parts down..... And in a few months, that'll get destroyed, too, and I'll be looking at making one.....

I've got a RanchHand bumper on one, Buckstops on a couple, and several with some bumpers I made several years ago when I had a welding/fab shop... . I don't have the time to fab much these days, so the Frontier bumpers are what I usually use. With hired hands, I have to have something to protect the truck from trees and cows..... It doesn't take long at $50 a whack for a good used bumper to pay for itself in headlights..... :{
At the LMC catalog, I think it's on page 14...
http://www.lmctruck.com/icatalog/de/full.aspx?Page=14 Page 13 shows a full skin covered bumper... . Is that their design or the sport bumper?
I've also seen fully chromed bumpers with no plastic on them that look pretty trick, IMO. I'd like to have one, but they're just plain not tough enough for me. I'm kinda a chrome *****...

I like the chrome mirror covers, window trim, polished aluminum wheels, with black bumpers and steps... . And don't even get me started on my KW..... You could signal the space shuttle with all the chrome in the cab of that thing... ... . :-laf
