My cowl reads ST70 49487 EUC118410 BDY TR Z698 10B 19 B PNT oK, MY QUESTION? It clearly indicates on the literature that 1970 Buick Riviera's did not come with the Regal Black color, this one is black how can it be, do I have the only black Riviera? , also on the trim it starts with a "Z", what does this mean?? Gord
Hi Gord - Contact the Sloan Museum at ask for the 'Daily Car Reports' for your model. It's $5 per photocopied page. Ask for the page with the paint code breakdown. Then you can see how many were made. I've seen many trim codes that started with 'Z' and I still don't know what it means. Sorry.
