Have an older Campy Rear derailleur (picture below) and it does not have the mounting bolt. How do I tell which bolt I need and where can I pick it up?

That looks very much like a 7-8 speed Chorus rear derailleur that I had not too long ago. I'm not sure where to get a bolt, but I have had luck getting little fiddly bits from Loosescrews.com

go to http://velobase.com/ViewComponent.aspx?ID=9F7FB5DD-6E42-4F07-8F3B-F2C7B6B1DBD0&Enum=108&AbsPos=14
and look at the pics. From a cursory glance, I'm saying it might.

Ya judging from that pic it looks almost spot on

Agreed. Definitely looks just like my late 80s Chorus short-cage derailleur--in which case, you should see an "A" and "B" on the side of the derailleur near the cable entry.

Doubt it. I don't know what that fits, but the nut head is stepped, and it tapers to the center. The Chorus is domed.

Good observation, guess the search continues

I was wondering why I was the only one that thought it was completely different. I've been kooking for that derailer. It will handle my triple without the long cage.
