Jennifer I don't know if you have made your purchase yet but I can recommend both of those companies as I have bought many parts from both rebuilding 2 Airstream trailers and the b190. I know Steve from Vintage Trailer Supply very well, even before he started his business. His prices may be a but higher sometimes but it is a terrific company and will treat you well. But really I don't think you can go wrong with either. Good luck!
