The number usually referenced is a shortened version of the VIN: the last 4 digits. This can be located on a metal tag on the top of the dash on the drivers side, on a tag in the driver's side door jamb and stamped on top of the foot box in the front trunk (may be different for this model). As you may or may not know the push button models are fairly rare which makes even a rough one a good candidate for restoration. And this one looks rough. It also appears to have had some modifications made. More pictures the better. Ideally you would enlist the help of someone knowledgeable about Panteras to give it an assessment. California is the epicenter of the Pantera world so it shouldn't be hard to find someone.
