Is your Kombi the one in your avatar? You say it's complianced as a 2 seater but if it's the one in your avatar with original VW rear wing windows, that means it is either a Microbus or Kombi. Only a panel van (no rear windows) or ute would have been originally complianced as a 2 seater; a microbus would be 8 and a Kombi at least 5????!!! There's something weird there. If you put an original Kombi rear bench seat in it, that locks into the original floor clamp recesses, and fit seat belts , a blue slipper can change the details back to what it should be - at least a 5 seater. You need to speak to a blue slipper who knows VW Kombis and the rules around them, because many blue slippers haven't a clue regarding Kombi's and ask for engineering certificates when they're not needed. Oh bugger, I just realized you're in SA not NSW...... So then I can't help you, sorry. I was gonna give you the details of my Kombi friendly blue slipper..... Good luck with it. The above questions regarding your Kombi being a microbus or Kombi should still apply in SA; originally, they would have been complianced for more than 2 passengers, ergo, you should be able to demonstrate that to the SA authorities and get the compliance modified??!!!
