replacing front bumper

I have a 2010 Tundra with original resin front bumper. The original front bumper is one solid piece including the valence.
I want to replace the resin bumper with a steel/chrome bumper. I bought the valence separate, from the steel bumper but I do not know what pieces I need to attach the steel bumper to the front.
What items/pieces are required for attaching the steel bumper to the front?

 

this might help
it has the steel bumper first but scroll down and you will find the resin bumper. Should be a mtter of finding which parts you have are common and which ones are needed.
