how do i raise the bumper?

So I've been going through looking at peoples rides and I've come to a conclusion that my bumper is way too low. Everyone that I've seen whether its the stock bumper, or yota, ect they are all snuggled up tight to the grille. Is there some great secret to doing this or an adjustment on the mount? Also where can i find a billet or phantom grille for sale? I've looked through older posts but the links have expired. And i know that i could make one but i don't wanna mess the grille up if i don't do it right!

There are 4 bolts that attach the bumper brackets to the front frame rails.....two of them are accessed from inside the engine compartment, and two are accessed through the rubber/plastic valance that is below the steel portion of the front bumper.....through the vent holes in it.
All 4 of the bolts have a 17mm head on them.
I would loosen all four of the bolts, then lift up on the bumper while you tighten the 2 bolts that you get at from the engine compartment.......those 2 are screwed straight down from the top and into the top of the frame rail. After you tighten those to the point where you have the bumper sitting where you want, then tighten the 2 bolts that come in from the front of the valance area.........tighten them up and then tighten the other 2 in the engine compartment all the way.

Here is a pic of the 2 in the front.......the bumper and grille are removed here, but just look through the front of the plastic valance and you will see your 2 bolts......if they're still there!



You can see one of the upper top bolts here, circled in red at the lower right side of the picture.
