Possibly, or a knock off from this company.

All mustang parts made by this manufacturer have long since been discontinued. They sold them in the aughts as a full bumper cover and as a separate add on valence. They stopped producing the add on piece when people complained about fitment issues Those people wanted to make a one piece from the add on valence and their existing bumper cover but the cost of labor well exceeded the cost of just buying the one piece, but they refused to believe me and take my suggestion, instead they decided to go the other route, then get legal when it wasn’t absolute perfect (show car)
I’m surprised you found one in such great shape. Where did you get it?
My suggestion is to remove the bumper cover, install the valence with permanent adhesive, fiberglass the inside of the bumper and valence with a lot of resin and a metal screen, then decide if you want to utilize the existing screw holes for additional strength, or just fiberglass over it. If you intend to back into any spaces, then I highly recommend reinforcing it as much as you can.
I have had my 94 since 98, and almost everything is from that company. I’m on my 3rd front bumper. But my rear which looks like the one piece version of that has been installed since 2003. Bumper has over 100k miles on it, so I know they can be somewhat durable.
