Dumb Mopar moves - this should be fun

when i started getting into A bodies i bought a 70 Duster 340 project car, i started taking it all apart and noticed on the K frame that some idiot welded a washer onto it.... Well i said to myself get the grinder and get that stupid thing off of there! I really didnt see the sense of leaving it there cuz it served no purpose so off it went into the garbage... i stood there so proud of myself, i was on my way restoring this mopar and the first hurdle was behind me... hehehe what a dope !!!
I did the exact same thing to my Duster. Had no idea what it meant at the time.
