Can anyone with the decode books tell me if there was ever a 2 barrel carburetor with the number 70561114 ever produced? I am looking for a 2 barrel for my 71 Chevelle that is supposed to be 70411114, and I have found one that the guy says is from a 71 El Camino with 70561114. I was wondering if maybe he was just reading the numbers wrong since the last numbers are the same, or if in fact his number was a good one?
