We are in need of one and notice that they typically include a thin blade with inserts, and a mounting block that somehow mounts in the turret. I have not seen any bolt holes that would mount it to the turret so curious how they would mount? My OD turning bar channels in the Turret are 1.50" so it accepts .75" turning bars and the clamping wedge is .75".

So do these mount blocks bolt in or is there some other item I need to buy? I have an older Mori SL-15.
