Glen:

I agree with toomanybirds on this one.

If you had a fixed fan like a non A/C car then it would mount with the spacer and long bolts with lock washers. Otherwise studs with nuts and washers.

Brew: I think you are looking at fixed fans not viscous coupled fans like an A/C car would have.

I used to snowmobile in the UP all the time but more on the east end. Not much further west than Munising. I sold my sled last year due to lack of use. If I decide to go again it's cheaper to rent for the weekend than own one.
