Well I am not a Pro at this impeller kit business but will be an experienced amateur as I've already did one, and have 3 more to do, may be more after.
You can't cut this stuff with a utility knife, to difficult and not a straight cut. You need a small saw with fine teeth. A hacksaw blade in a hacksaw holder would work, not in a hacksaw frame.
You could drill 2 holes and use a jig saw to cut the slot or drill 1 hole and use a jig saw. I will be trying both however I will first do a paper mock up and use that as a model and guide. I'd like all the holes in the impeller blade to be in the same location.
I used Truss Head Phillips screws (large head, eliminates washers) and 2 way reversible lock nuts (same but as shear pins use), you can also use Prevailing Torque Lock Nuts, you don't need lock washers.
On two of my snowblowers I'm going to put an aluminum strip with the bolt holes in it across the top as a "clamp" to hold the rubber down. I figure there's less chance of the rubber tearing.
