https://atlanta.craigslist.org/nat/cto/d/acworth-1969-convertible-buick-gs-400/6808472574.html I know it’s a long shot but there was an orange ‘69 vert sold north of Atlanta several years ago. Original color was Crystal Blue. A member here had the trans from it, snd it was a BB. That car might be this one. If you’re into mysteries and puzzles, this might be a Stage, and if so, the trans that proves it (see VIN in thus thread) is probably still available. http://www.v8buick.com/index.php?threads/1969-bb-transmission-th400-found.303740/ Patrick
