The original spark plug specified was either a Champion RN10PY4 or a NGK PGR5C-11, both of which are a double platinum plugs. The Champion part number is still valid. NGK now specifies a BPR5ES-11 plug as the replacement. I am sure you can cross reference either of these numbers to any brand you prefer. I think the Autolite equivalent is a APP64 plug. Set gap 0.039" to 0.044".
