Hey, over there,
As I know, there is no supplier for these certain parts, at the moment.
Even the guys from Netherlands do only sell the small one for hot bulb, etc.
From time to time you can find a used one on ebay.

This seams to be a general problem on the later Bulldogs. My radiator must
have been leaking, as somebody fixed it with a brass plate and liquid metal.
If the egdes, guiding the o-ring gaskets, are not yet complete gone, you could
try to use some liquid seal, additionally.
If you like, I could paste some pics of mine, showing the repair.
