73 340 Duster being restored in Maryland

so the car should be getting epoxy primer within the month for sure. Now we need a color choice. While I thought it was already decided that the original JA5 Silver Frost Metalic was what it was going to be painted, my dad is now 2nd guessing and is trying to convince me to go with Sassy Grass/ Go Green. Can anyone tell me a percentage of dusters painted JA5 since you sure dont see many I assume its kind of rare I guess you can say. If he sees that it might change his mind and the original plans would be back.
