Randy, I was quoting directly from the Service Counselor.

Looking at my 1962 spark plug chart, both Champion N8 and N18 are listed, the N18 being the slightly hotter plug, otherwise identical. The N18 is listed as equivalent to AC 46XL and the N8 to the AC 45XL. There is no AutoLite equivalent given for the N18 but AGR51 is given as equivalent to the N8.
