I have a Cyclone RD that has a crack in the body at the high/low positioning screw threading - but which appears otherwise intact. My plan was to keep it on hand for spare parts, but if it means the difference between completing a project and not, I'd be willing to cannibalize it.

If the search for a replacement fixing anchor comes up empty, send me an inquiry. To remain legal with Dale, I'll list the asking price for this at $1.00 plus mailing at cost.
