PY Online Forums - Bringing the Pontiac Hobby Together - Looking for '73 Lower Reinforcement

I'm looking for a Lower Reinforcement (488564) for a '73 Firebird. To allow me to remove ~85 lbs of weight off the front of the '73, I'm attempting to use '71-'72 bumper brackets & some fabricated intermediate pieces to get rid of the government mandated 5 MPH crash steel. But, to mount some parts, I need the lower reinforcement. I don't intend to use all of the steel, but will cut it apart to use two portions to allow the grills to mount properly.

Because I intend to cut it up, as long as the sections where the lower grill brackets mount are good / straight, it should work for my intended purpose.
