Parts suppliers - all types of things

Hi Volks,
You may or may not have noticed we are starting to get our Mk1 back on the road and as such I need lots of bits. Problem is I don't know a good Mk1 parts supplier from a bad one so I need some help.

Volks have already recommended GSF/Euro Car Parts for brake bits but what about the rest.

I need to get dizzy cap/leads/plugs etc (basic service items) would you use GSF or Big Boys Toys or is there a.n.other I don't know about. Do VW still stock Mk1 watercooled stuff?

I'm basically after a list of decent suppliers for the following bits.

Electrical stuff
service stuff
brake bits
body panels either VW or pattern
auto breakers for 2nd hand panels

I know these are probably very simple questions to you volks but the water cooled scene is a whole new ball gme for me and I am on a steep, rapid learning curve.
Cheers,
Neil
