billypants-t80

Hello everyone, I've just bought a T80 too, it seems like a fun little thing and I can't wait to get it on the road. One prob I'm having is whenever I call dealers for parts they tell me the machine was only ever made between 1983 and 1986 but my log book and reg plate say it's a 1996 model so I can't sort out parts. The frame number starts 35T which one dealer says makes it a 1983 but what's going on with all these dates ? ? ? can anyone shed some light on this for me ?
