Expert-X Wheels - Skidoo?

[tonykof]

Hello,
Anyone know what size & kind the wheels (both back wheels & idler wheels) I heard once that they are ski doo?? Obviously I can easily measure the outside (6 3/8") it's the bearing part I'm not sure about.
I have a friend that offered to make me some aluminum wheels if i got the specs for him..
Thanks
Tony

Also for future reference how about hyfax?? Ski-doo? What model & year Ski-doo?
