Replaced my dented up bumper on my 05 with a 2008-2012 bumper. Turned out pretty good, sticks out just a tad far though. One day Ill drop the mounts and drill new holes. Other than that it lined up just fine.
I need to do body mounts BAD. I am thinking about going with poly, I can't swing the $400+ OEM rubber mounts right now. I just hate that I have heard about fitment issues and squeaks. The stiff ride from poly mounts doesn't bother me... its a driving brick, not a Cadillac. Anyone put poly mounts in their trucks?
