Where to get these step bolts?

[72Blazerod]

Hi guys,

I was wondering where I could get the bolts (and nuts I guess) to repair my front steps on my 1986 Soveriegn? (See the pics to see the bolt I mean). As you can see in the pictures, one end of the bolt has sheared right off.

I live in British Columbia, Canada and we don't have the same hardware store you guys have in the States. Will I have to get them from Airstream directly? Does anybody know what these cost?

Thanks,

Rod
