This first photo is the drivers side.
I need to repair the floor section that you can see has a hole in it as well as the metal piece that goes in behind the outer rocker panel all the way to the back.

I'm not 100% certain that I've found the right part, I assume the part displayed is slightly different from what I will receive. (maybe they only had a picture of the same part but for a different year) The part is called a "Driver Side Cab Floor Exterior" and states that it is for the 67-72 chevy pickups. I just want to know if what I found is correct. It costs $57 on Top Banana.

Any input is appreciated.
