I'm gonna have to do some digging, but a friend of mine sent me a link to a post on FSB (fullsize bronco) about welded versus bolted on custom fabbed bumpers. I'll search my MSN archives, but I think the read would be really interesting for you Griggs.
I'll get the link posted soon. I have to finish editing photos for Zach (redneckstone).
what the hell, I'll just post the messages up:
Jason is my best friend's brother. Drives a 97 4x4 F-250 superduty ex cab short bed.
Somewhere I belong is me (having one of those days - Linkin Park was soothing it over)
We were talking about my front end and how I'd like to modify my westin grille guard so that I can bolt it to where my tow hooks are versus having it attach under my valence with brackets (like it currently does) which equals reduction of angle.

10/22/2006 8:59:49 PM Jason fyi
14 PM Somewhere I Belong interesting
22 PM Somewhere I Belong porque
29 PM Jason cuz it flexes
34 PM Jason and bolts allow flex
46 PM Somewhere I Belong whereas the welds could warp and crack

10/22/2006 9:04:12 PM Somewhere I Belong damn it I should have gotten a FSB
10/22/2006 9:04:20 PM Jason But with all due respect I would rethink the connection to the frame rails. One or two bolts on each side IS insufficient and welding is a bad idea too because like it or not, there IS going to be some flexing especially under winch loads. Welds do not do flexing very well.

I'm trying to locate the link he sent me where the guy had drawn up in a CAD program his mounting points, detailing the weakness etc. Not able to find it yet.
