02' KTM 520 fit kit?

I have 02 KTM 520. Anyone know if the KTM fit kit will fit with no modifications.
Timbersled shows the KTM kit to fit 03' and newer bikes. T
he frame and swing arm appear to be the same part on the 02' as on the newer KTM's. I called Timbersled and they couldn't say without looking at the bike.
Anyone have experience with this.

Thanks for the info. The used kit I'm buying comes with a KTM fit kit, I'm assuming it will be for the newer bikes that look to take the 17mm bolt. If I need the 15mm bolt is that all I would need or would I need a whole new fit kit that is build around the 15mm bolt.
Sorry about the dumb question. I know nothing about the timbersleds kits at this point. This is my first try at it. I'm looking to be ready with what parts I need ahead of time so that I can get on the snow ASAP with it.
