8ax/88r clutch

[arcticsrx500]

I did bought a lot of old yamaha parts, but when i got it here, there was a new primary clutch in it.not yp but yxr i think

The plastic bags has the number 8ax spider and sheaves, but the cap has 88r. The was also two oem buches with it.

What does this fit?

ex 570?
vx 750?
vx 800?
srx 700?

Can it be used on every yamaha snowmobiles?

thanks for all answers.
