6sp derailleur w/7sp cassette?

Hi, I'm looking to replace a Shimano Sora derailleur with an older Dura Ace 6-speed derailleur I came across on eBay. I have a 7-cluser Dura Ace cassette, does anyone know of any compatibility issues? Sheldon Brown has a good article that I hope is correct, but I'm not certain what year the components were manufactured. Any experience or insight is appreciated.

The pre 9 speed DA RD have a different throw ratio.You 'll need 7 speed DA shifters to go with it.
