Hi Paul, I don't have the answer to your question, but you will get more replies if you post it here on the group. http://www.v8buick.com/index.php?forums/interior-city.21/ Good luck, Gary
My 78 Turbo Coupe had a label on the inside of the trunk on the underside of the deck lid. If there isn’t one in the glovebox, I’d look there.
Thank you everyone, we found it, it was attached to the cowl panel below the windshield. It didn't have a SPID label just the trim tag. I'm still looking for some documents that may list the options and prices for Buicks, similar to what GM Heritage has for Other models. https://www.gmheritagecenter.com/gm-heritage-archive/vehicle-information-kits.html Paul
Thanks, I'll look through, was hoping there was a book that covered many years of options and prices... Paul
