Front Bumper not straight adjustment?

Good Morning - Last night I installed the TRD grill and noticed the bumper and end caps are not level...and of course is all I see now. I found this thread which I think is a similar issue.

If this is a similar issue then would adjusting the end caps automatically adjust/straighten the bumper or does that have to be adjusted independently of the end caps? I'd like to adjust myself if possible so any recommendations or tips are appreciated for getting this fixed, thanks!

 

Figure out how much you need to adjust it. You will need to take grille off and the plastic pieces below headlights to access bolts. That is what I did. I had a slightly larger gap on one side. Yours looks worse then mine.

 

So is the bumper adjustment separate from the end cap adjustments?

 

Don’t run your fingers towards the rear of your back bumper between the bumper and body..you will see what I mean if you do...
