Hey andy,
I see you're in Ontario (I'm located in London) and there's a British cycle supply place in Lucan called Walridge Motors (www.walridge.com) who (I'm pretty sure) will mail any parts ordered. I haven't ordered anything from them yet but if you have part numbers, you're good to go. They have parts catalogues too if you don't have the numbers (Walridge is cheaper for the parts book).
There is also PD Restorations in London who deal in British bikes. Good guys and very knowledgeable. (www.pdrestoration.ca)
