If my memory serves me well I have a 009 on it ? It's definitely not a Porsche item.
US swap meets are going to be hard to get to because I live in france.
No prices on the vintagewerks website, but there is a reputable porsche distributor specialist here in france and he said it would be around 450-500 €uros for parts and labor.
This seems to be an ok deal for this Werks rebuilt one provided job was done properly
