Emery,
I have a rotary installed by Quella.
It is a Sanden model SD508, Sanden part number S8390.
Two groove pulley.
Cross referenced to a 1981-1987 Subaru Brat.
I am positive about the Sanden part number, not positive about the Brat cross reference.
Go to'www.master auto parts.com' and they have a rebuilt for $74. They also show up on ebay now and then.
