I believe you are right. It’s a G9G247895 would be appropriate for a Road Runner built at the St. Louis plant with an SPD of 409. It may be marked HP on the pad next to the distributor.
9C247895 would be out of a Chrysler with an SPD of 322. It would not be marked HP on the pad next to the distributor.
Look at the VIN tag on your dash - Is it RM23H9G247895 (or - RM21H9G247895)?
Edit: -Probs not as it looks like a blue engine painted orange?
