Hi Tommo,
I would say your first port of call would have to be
Triumph-ant down in South Wales.
I visited there a couple of weeks ago and it was an aladdins cave!
Failing that I would have a search for a write-off/salvage auction site
Just had a quick rummage through ebay. How about this in the uk, either as the item, or as a place you could contact?

something in the states as well

Best of luck
