There are two in WI that I know of. One being us. We try to carry the best parts avaialable.
If you are refering to Van's I have been happy with the parts we get from them. There are a few pieces of theirs I do not carry because we have a product that is more correct then what the make, but I have been start to carry more them as well because not everyone is doing a concours car and don't mind saving a couple of bucks.
