Comedy reply: The tube you're thinking of probably starts with 12.
Somewhere out there is a database that you can enter 3 or 4 known tubes and get a list of units that used them. Possibly radiomuseum?
Being a pontiac product there's also always the chance that someone still has access to an old GM parts-list for a vehicle that came with it as standard that might list tubes. (It would not surprise me one bit if they had GM / Delco / Mopar branded tubes just because they could.)
