Is this factory? 1974 fixed bumperbumper

Thank you for clarifying what is obviously a mess! i noticed this morning that the brackets are loose So it's good i didn't put jack stands under them.
which leads me to..... my '75 valiant has the bumper shocks. Any easy way to toss that garbitch and get the old school mounts? I'll assume I need a '74 bumper, and brackets, but adding the holes?

I'm tempted to swap this bumper and brackets onto the '75 and put the shocks on this car
