On AP I've learnt more about pin's & how to fix/ improve them than I thought I ever would. Member's are willing to freely share their knowledge & experience - they've been very supportive & patient with me & my questions. And I love reading even the old posts - especially the resto's - I really admire the patience, skill & attention that go into these. Retropin has been a standout for me - I love reading his repair stories - but there are many more. Top forum & great thread.
