Question: 1986 Spark Plug Question - AC Delco Rapidfire

[chris123]

On my 86 Convertible with the aluminum heads, I purchased the AC Delco Rapidfire Spark Plugs, the #1's which are GM part #: 19250960; I've checked with a few sources and they all seem to agree they are the correct ones. The AC Delco plugs that came out were part #: 41-629, and have the small metal washer on them for proper seating; the Rapidfires do not have the metal washer; just wanted to make sure these were the correct plugs.........

Regards, Chris.
