'Easy' depends on your tools and experience. It's held on with three rivets. You should be able to drill out the rivets, pull the broken pin off, then rivet another one on.
The part number is: 98655154700 and it should cost under $5 plus shipping (or pick it up at a dealership?).
If it was me, I'd make a shopping list of enough things to get free shipping - air filter, oil filter, crush washers, O-rings, and a couple odd bolts....
