Ok. Here is my contribution to the plate issue, costs under $6 from Lowes.
First pic is of the stuff:
1) 1/4" HDPE water line used as spacer on bolt head so bolts don't stick out of plate holder and as compression piece between washers, so grill is not damaged.
2) 1/4" x 3" carriage bolt (2), may switch to regular bolt for tightening purposes, hard to get behind grill without help.
3) 1/4x1-1/4 fender washers(4) 2 painted black.
4) 1/4x1-1/2x1/16 rubber washers (4)
5) 1/4 x 20 nuts (4), may try nylon lock nuts with bolts and help(long arms).
First put small spacer on, then washer ,then rubber washer. Fit this through 2nd opening from the top and push through top opening, two hands, no dropping.

You have to kind of work the rubber washer to get it to stick out straight. I used a couple larger ones from my first attempt to mod.
Put grill spacer on then rubber washer then washer then nut, tighten. As you can see from the pics I had alread scribed the bumper where I wanted to line the bolts up, that saved a couple seconds. Just kidding, it's a reflection off the bolts........are you kidding me!
Put the plastic plate holder on right side up, the groovy thingies line up and the top slot goes on the bottom cross bar piece of the grill. Washer and nut to secure.
Any improvements or suggestions are welcome. As you can see by the plastic plate holder, I chopped the cr@p out of it. You will not need to cut yours as much. I did not want anything touching the paint or close enough to vibrate and rub at highway speeds.
As I posted earlier, I am looking to buy another stock plastic plate holder........
