Mr. B,
Welcome to the forum.
USA is kinda big, mind sharing approximately whereabouts?
If you're looking for fastener suppliers in the US, britishfasteners.com is a good place to check. Of course, you could also go to a general British motorcycle parts supplier like britishonly.com or klempfs.com. Also, check out the recent thread here titled "Thread thread". It was focused on packaged assorted fasteners, but some good links for specific pieces, as well. With any luck, the right fasteners will be the hardest thing you have to find. (Fat chance.)
We all like to see photos, particularly the ones showing the bike transforming from rust to righteous.
