Is this factory? 1974 fixed bumperbumper

While under the car for a k frame swap, I looked up and noticed this fender mount extension is a different color. The hardware appears to be oem style bolts.

The front bumper is a fixed mount, no shock absorbers. Would this car have had bumper shocks from the factory? Frame rails show evidence of a hit but front clip is straight and I see no repaint indicators.

I'm not a body person, so I don't look this stuff too often.
