I bought a set of bumpers and I triple checked they were for my truck. Mounting kits and all.
front bumper and kit went perfect. Aligned nice. Rear bumper is similar, missing a support and the supplied brackets will not align to any holes no matter how you flip or move it. Anyone have any ideas??? Do I just clean up my rusty old brackets? Thanks

 

Any pictures?

I usually always opt for cleaning up the oem parts if they aren't mangled or rusted through and can be reused.

 

I agree with Edgethis, the OEM parts are nearly always better (and stronger) I just media blast prime and repaint good as new and generally cheaper and pics would be handy.

 

I prefer OEM rear bumpers too, but there aren't many of them that aren't dented, bent, twisted, etc anymore. Took me 3-4 years to find a nice one.

Is the LMC rear bumper the Westin FEY one sometimes called Deluxe XLT? There are 2 or 3 bracket kits for that bumper for use on Ford Chevy and Dodge. I had it at one time with the Ford bracket kit and it fit just fine.Verify you have the Ford bracket kit.
