Wheels and OEM

[Hilux2400]

I am considering buying some wheels which are claimed to be original Porsche fittings. I can see from the photos that they are made by BBS and are the correct size and offset.

I have asked for the Porsche part number, either 993 or 996, but this info is not forthcoming.

I assume that all items which are original Porsche would have the Porsche part number?

Thanks for reading.
