I am going through a restoration of my 67 Poncho and you can still get a lot of parts for your car. However, it depends on what parts you're talking about. Maybe you can be more specific. Just reminder that most of the chassis, suspension, brakes and floor and trunk panels are the same as a 1967 Chevrolet Impala. Antique Chevrolet was very helpful and I found that Shannon was very knowledgeable about what Chevy parts will fit on a Pontiac.
Jonathan, The reproduction floor panels from a Chev Impala will work, the rockers might work and if you needed trunk repairs, the Impala pans should also work. If you need quarter panels, there are patch panels available. Not great but workable. Any other body parts will have to be found, used. Some interior pieces are available and engine and suspension are available.
