Noob RD Question: Missing Part?

Had a bungee cord in the road make quick work of the RD on my Nishiki Sport last week. Quick stop at the parts bin yielded a few good condition long armed rear derailers. I think I'm missing an assembly though that goes in the dropout or at least a longer screw. The old derailer had a thick screw that went directly into the hanger that's part of the frame:



Here's a picture of the derailer and these two small metal plates with the screw that was in the dropout but the screw is way too short to fit through the derailer and dropout:



Is there something I need to buy or do I just need to find a longer screw that happens to have the same thread? What are those plates called? My local lbs doesn't do parts (couldn't even buy a replacement axle) so when I go somewhere else I'd like to ask for whatever I need by name and not by 'do-hickey' or something

Thanks!

You got the wrong rear derailleur. Your frame has the derailleur hanger attached to the dropout. The derailleur that you bought has the hanger connected to it. Rather than a missing part you actually have too many hangers.

My mtb (same SIS derailer too) has the same looking assembly (two plates with a screw in the middle on the dropout). There's no way of putting it on?

What are those two plates for anyway?

Not that great of a derailleur to begin with. I would find another of better quality. You can tell most of the low end stuff has the hanger built in like that, for going on bike without forged drops and integrated hangers. Hit your local bike shop, they can help you find something more fitting for that classic ride.,,,,BD

For $17 + shipping I'd just buy that sweet Deore RD at nashbar.com. Levels above that sis trash.
