Reducing the Beak?

My ‘74 must have been an early one, still has the normal ‘73 front bumper, no shocks. But that rear bumper has to weigh 100lbs with all the dirt and rocks caught between the chrome cover and the reinforcement!
i was shocked at the weight of my front 74 bumper and shocks. i bet it was 100 lbs between all of it. MOSTLY the inner structure, but the outer shell was alot too. spring mount surprisingly weren't as nuts as I thought they would be.
