Good news, I found the oil filler cap! Sorry no spare dash speaker.
I made it up to Auckland in the Beat earlier this year, will let you know if I head up there again. You mentioned that you had a scored a free Beat for parts, you wouldn't happen to have a spare oil filler cap by any change? The one for topping up that is accessed from the boot.
Hi, and welcome to U-UKHBC. Let me know if you ever make it down to Wellington or if you ever need and help with your Beat. Cheers, Julian julian@vehiclesecurity.co.nz Tel: 0212425276
