Rega tonearm swap ~ simple advice needed please!

Hi,
Thanks for looking ...

I want to swap over an RB250 pillar/collar fixing from a Michell Syncro to a Roksan Radius mk1with a RB100 with 3 point fixing.

... Then l want to put the RB100 on the Syncro.

Advice much appreciated please!
l guess there's a Rega expert out there?

Thanks, Paul

Fitting an RB250 to a turntable with the later 3-point fix is just a matter of putting it in't hole and tightening up the screw collar. Geometry is the same.

Dave should know as he’s sold enough but, just to iterate, he’s quite right. Going in the other direction you need to add the three screw holes.

Thank you guys.
Just needed that moral support beforehand!

lf l need spacers, l shall go to Radlett! :)
