Can anyone provide me the part number of the bolt in the picture with the cotter pin? It's where the D-clips from the snowthrower attachment attaches, but on one side the bolt is missing.
I only remember two mounts like that, seems they were part of a mounting kit for the blades, blowers, etc back then.
The numbers I come up with were M96916, and M133167, they looked the same but were different sizes, maybe the attached will help -
