Alternator mounting question

I've got a '74 Dart 318 with air/conditioning.

Does anyone have a good photo showing how the pivot bolt or bolts on the top are supposed to go. Mine currently has two different bolts up there, and may be missing a bushing as well?

The belts started slipping and I discovered that the front pivot bolt had fallen out. I've replaced it, but something still doesn't seem quite right.

Thanks,
