So silly and I could not find. So I had removed the front bracket and now adding it back.

Can someone tell me which screws or bolts hold the bracket to the bumper/grill?

I have the bolts for the license plate to the bracket but totally forgot which ones for bracket to grill

 

Is there anything that goes to the back of the grill? also since it doesn't seem I have any screws that are long enough

 

Sorry, can't help with part numbers, but why not remove the bracket entirely and just attach the plate directly to the bumper holes? This is what I did and it looks much better (not as good as no plate, but better than stock bracket). You will have to drill the plate since the bolt location will change, but that is easy.
