Here you go Dave: www.gaugepods.com/buick.htm I have the dual one myself. Just so you know it mounts OVER your stock pillar, it is Not a replacement just a cover. Some have dislikes in the way it looks once mounted. It does not wrap around the pillar like the factory piece does.
I have t-tops so I had to cut mine, then touch up the cut with sem paint. Not a show car install but I am happy with mine.
Thanks guys, I did see one at the Nats a few years ago that did replace the entire A pillar trim piece, thought that would be a cleaner install. I'll call around. Thanks again
If you have a T-roof car Cotton has a "T" roof mounted twin gauge pod. It takes the place of the plastic T piece that is screwed to the roof above the rearview mirror.
