i have got a version 6 sti classic

and the clutch is a ap racing one code cp2000-18

codes on the other parts
clutch plate cp6452-6
clutch cover cp4150-2
bearing cp6150-19

I'm not sure, but i think the AP web site lists all the numbers for Organic and paddle parts.
The only person i know who might be 'open' to ask today (sunday) is an email to Alyn at AS Performance - Rally Motorsport Specialists

Ace guy.
