Hello Martin
Thank you for the incredible info. You're a real gentleman and a scholar!

I'll give Nengun a try this weekend.
I'm quite baffled though - I didn't think the AZ-1 had a brake drum option! I thought it was brake discs all round. Yeh - that got me scratching my head.
FYI, the AZ-1's VIN starts with PG6SA while its Suzuki "brother" - the Cara - VIN starts with PG6SS.
