let me check....this afternoon and i'll get back to you. I'll try to take a pictures of it. It may just be a code and not say anything about the paint code. But I had a dealership guy show me one day....so that's the only reason I know where its at. I'll let you know this evening.
sorry, I didn't get you the pic. But I looked at it and its in the middle at the bottom line of a white label (inside the door) it says paint: PR4 on mine. The label is where the locking mech on the door. catches the striker. Don't know if yours is different, but that's where mine is. Hope that helps.
Go to where you are going to get the paint mixed & ask to see the color chart for the year jeep you're going to paint. Or the counter person will know where to find the code, usually that paint chart book has the location of the code.
