Outdoor Power Equipment and Small Engines - Snowblower chute fasteners

Hi, I have a 1970's Gilson snowblower (model# 55012). I am wondering what the little fasteners are called that hold the chute on. It has 3 such fasteners. They are a bolt that has threads towards the head and then the threads end and the rest of the fastener is bare. The threads fasten into the chute base and the bare rod-like part then goes into a brass type of race/bearing that rides in the channel that allows the chute to turn.

I can't picture what you're describing but generally speaking they're called chute ring shoes. You can try a Toro dealer for Gilson parts. Lawn-Boy bought out Gilson many years ago and Toro in turn bought out Lawn-Boy about a dozen years ago.

After consulting with a Gilson collector at The Snowblower Shop:

the parts I am referring to are known as dog screws and roller pins.
