I have 2 questions. 1. The brackets that attach the bumper to the body/fenders have broke off both sides of the front bumper. This is causing my front bumper to sag a little and my fogs shake when driving. It's kind of annoying to say the least. What would you guys suggest to fix this issue? The Jb plastic weld stuff, Emblem glue, etc? I need something that won't break right away in the cold, it tends to get a little nippy here in MN. 2. There is a shield that is behind the bumper in the lower grill. Mine is mostly gone. What's left shakes in the wind and I can feel it while driving. I have a shield out of a swb 4.2 TB. It looks like it is meant to funnel air through the ac condenser/ lower radiator area. Is there a difference between the 4.2 and the 5.3 in regards to the radiator/ac condenser/lower grill area? Thanks in advance for any help.
