i got a Bell 22-1-46230-8 Adjustable Mounting Bracket for License Plate Frame from Auto Zone for $8.99 and it is all chrome and did a great job
I used one of the front lower holes on the GM bracket and it covered up the right hole
i bought this R used so it already had 4 holes in front from the OEM plate holder
it can be angled on all 4 mounts so it is very adjustable and you can even mount the plate on the lower holes if you want to. lots of possibilities. it comes w 2 threaded w lock washers and bolts and 2 self taping all chromed
comes w the allen wrench too which is in the glove box
looks great to me, out of the wind stream and gets the TX peace officers off my back
this is very solid and cant complain w how easy it went on. took less than 20 min
Bracket
excuse the weird angle taking the picture. i had a car behind me
