I have a 70 z with bright blue standard interior. I am looking to restore the upper and lower door panels. From everything I have found the reproductions for the upper are not a good match. I have also tried several dyes and they seem to be off a shade or two. I spoke with Just dashes and they will restore the uppers and lower and color match. Very expensive option about 1k. Question is just dashes the best and only option? to color match would I am thinking the back side of the plastic panel would be the best place for them to match from? any suggestion?
