I'll probably get the rear stems from DSS, and I can find the smaller Stanley items off of earlier US bikes, but the 400F headlight bracket with the smaller-sized crossbar for the winkers is UK specific, and I've been looking for a bracket for over three years now.
I missed the auctions because I am sick and I fell asleep, but I'll keep my eyes peeled, and if any UK members have a spare UK 400F headlight bracket, or know of one, please let me know.
