Unfortunately, no.
There are some generalizations that can be made about your car, that can be based on what year your car is.
Otherwise, to really be sure (as sure as you can with ~30 year old records maintained at Porsche), you need to order a Certificate of Authenticity. This piece of paper is AKA a "Cardex".
Current costs for a Cardex is running about a hundred dollars.
hope this helps,
