Afternoon project? 1973+ bumper reinforcment removal for weight reduction...worth it?

Yes a 73 plate is way lighter than a 75 or 76. Not sure if a 74 is more like the 73, 75, or 76
MY 74 was the heavier setup. Between the spring filled coil mounts, and the backing plate, it was every bit of the 86 lbs noted in post 11. I would have honestly guessed more. I also went fiberglass like post 11 above. If i was keeping it on the street, i probably would have just re-used the chrome shell, slid in closer to the body.
