Gene.... IF you haven't located a clock yet. . . I have this one. NOT certain what Year BUICK it fits, however, me thinx it is 68-69 style. I have a receipt ..it was cleaned. disassembled and converted to QUARTZ by THE CLOCK WORKS in West Bend, WI back in Feb 17, 1995. No P/N that I can find other than "434" on the backside. Almost square at 2 -1/4". NEVER INSTALLED. If you need it an you think it can work for ya, email me. Wheelz, Tampa Bay
