Stiffer rear suspension

What I don't undestand is WHY ANYONE would sit on the fender of someone elses 69 notchback Cuda? WTF?

Very close friend of mine , didn't litterally sit on the fender. Car is disassembled with sundried paint on it I'm saying that If I were to sit on it or put my weight on it as I'm 6 ft 235 lbs it doesn't move an inch
