Ok. This is straight from the 70 service manual for my 70 Barracuda.Under the "Low gloss finish colors" the line reads" Dove White, Chrysler code AB5EW1, Ditzler code-DIA 8745, Bucket seat hinge cover. Here is the label from the paint I used. It is a PPG paint but the cheaper Omni line.It is a base coat/ clear coat designed paint. You can paint it without the clear for a low gloss. You are supposed to add a small amount of an additive that make it tougher when you don't use clear. It is very expensive and I was only going to use a very little in the paint, so I did not buy it . The paint guy said it would be fine in an interior application.
** NOTE*** the code your are looking for is the W1. That is the one that will help the store mix the correct color. It is a common exterior color for 1970.

Here is the end result.IMHO, the Metro door panels are slightly more yellow than my OEM door panels. I'm making that decision by looking at the back side of my panels. The door pads that I bought from BE&A are whiter and match my OEM panels better. The seat backs from BE&A are whiter as well and seam to match the seats better. I have new leather seats from Legendary. Who knows if they are a perfect match? The way I look at this is simple. They were probably not perfectly matched when they were brand new. I'm just glad to have some new parts. I have had a terribly faded interior in my AAR since I bought it in 76! The Texas sun is hard on plastic. It looks better than it has since 1973 or so.

I have a glass bead cabinet that I blasted everything to bare metal. I shot white epoxy primer on it all( DP 48, I think). I then sprayed two coats of the W1 white on the part and let it dry. I masked every thing off and used black gloss out of a spray can on the buttons. The only thing I would change is I wish I had not primed the buttons in white. The black is spray bombed and it does not stick well. I nicked the button slightly and the white primer shows through in a small spot.
