The new alloys I've purchased have a centre bore diameter of 70mm that goes down to a 60mm:



Can someone please tell me if I need to get spigot rings to go into the top, wider bit or I need them to go into the smaller diameter part to reduce them down to 56.6?
Hopefully that makes sense!
Any help would be great, thanks!
