Neil,
Don't know if you have West Marine stores up there in Canada, but they
stock this part. You could probably order one from them
http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?productId=24883&catalogId=10001&langId=-1&storeId=11151&storeNum=10102&subdeptNum=10242&classNum=10248
but any store that sells sailboat rigging should have them available in
small quantities.
Don

Thanks much Alistair.
Good to know re SS. Thought to heat it, but had no idea how it would
work harden. Of course all this depends on whether or not this little
part is sold in lots of __ or not. If I have to buy a bunch then, I'm
out!
The crimping tool the the North Van marine shop will let me use, is
similar to this. i.e. the right tool:

The parts can be crimped on to the cable removed from the assembly so
no awkwardness.
And for sure. That spring is a fairly large gauge. It stays under
tension (compressed) when top down.
Neil.
