Rear license plate bracket 72 coupe

[Ripper679]

Hello! Quick question, I have a 72 coupe that didn't come with a bumper/valance assy. Putting it together, is there a bracket for the rear license plate? I bought the light/bracket assembly but wondering if there is an additional bracket I need to source? What's it look like?
Thanks all!

The bracket is an integral part of the rear valence
