You just need to find an industrial belt supplier that carries the Gates 3MR-2061-06 belt. It is 2061mm in total length, 687 teeth, with a 3mm tooth spacing, 6mm wide. I bought a bunch of them from SDP-si when they had them in stock. I also bought the belts and pulleys to change the Mongoose to a XL style belt, which is a little easier to find.
Ive had the same belt on my Mongoose for 8 years, so I think I am good!

Hi BeltFedBrowning yes harder than one thinks here in NZ , I was looking through the vario site at the tail mechisizem and spotted the gear set up if the frame spacing so are the same then it's may fit , all one needs to do is for the helix gear on the shaft and the rest would be all vario , have alook see what you think I don't need this stuf as my goose is all good but I was thinking ahead if ,,,,

Here is a thread where a friend of mine went the other direction. He put a Airstar belt tail on a Vario. This thread has a lot of info and part numbers.
