Regarding the blower-- I have an exploded parts diagram for the Kubota BX series snowblower, which I believe is identical to the GC series blower. It matches so closely that I printed it up and added it to my MF manual collection. I did get a set of shear bolts for same from the local Kubtoa dealer; they're identical, even to the silver & gold colors for auger & fan.
Figured it wouldn't hurt to have an alternate source for parts!
