Vixen Dovetail Base

Greetings,
I'm wanting to attach my 80mm Onyx refractor to a larger scope, probably my 6" f/12 D&G refractor. It has the Vixen dovetail. I'm not finding any original or after-market mounts or bases that would receive and hold this dovetail. Presumably, I would want a "Vixen-style" base to put on the larger scope, that would hold the dovetail of the 80mm refractor. Would someone be able to steer me to such a product?

Thanks!

Ken's rings?

Here's one with a 1/4-20 hole: http://www.scopestuff.com/ss_ds13.htm

You could also try Teton telescopes.
