I found a 72 cuda with a July 72 SPD that supposedly has "Y9#" on the bc sheet. Galen's book says it's "Show car finish". I'm a little lost on why the "#" symbol would be used instead of a number. My info is from a typed up decode that GG did and I have not seen the actual sheet. His info on the decode says "Show car finish # ?" Anyone else ever see this? Thanks.
