Well, I am about 50 minutes outside of New York city and I don't really know of many shops for Z parts that you can walk into and make purchases. However, if you need to order some stuff and have it shipped to my house, you can then pick it up here. It would not be a problem. How do you plan on getting all the parts back into Europe? PM me and I'll give you the details of where I live and my contact info. We should try to get together some time. Where in Europe are you and where in NY will you be staying? It is a pretty big state.
