Thanks Don,

Now I see.  Unfortunately all of the places you mention are in the US and
I'm not!   I'd also have to say that driving a VW, I rarely frequent RACING
shops, though we do have them in Australia.  I have a couple of places not
too far away that I'll have a look at.  This seems to me like a good
solution.

Thanks for the reply
