body by fisher

Good Day, I am asking this on behalf of my father who just bought a 1981 El Camino and was looking to have this tag decoded. Body By fisher 81 04B 1AW80 D170244 77D 16L 16U L AM6 4147 D91 16L 72U Any help would be greatly appreciated. Thank you...

Hey Guys, From the fresh new red paint on the camino, I was able to find the body plate for her. (It was black before and I couldnt read it...) I was hoping someone could decode it for me...I tried to google how to do it, but could only find it for camaros and chevelles. Or if you could...
