What is the bore of the hole in the boss of the part? My guess is that if it is 1.25″ (the pillar that holds the motor and grinder spindle), It (might) fit under the power head, the long screw would fit in the spiral groove, the small screwto lock on the outer dia of the pillar. the longer bolt would be on the bottom side. Don’t really know, I’v only got page three of the 1975 drawings (of three pages), I had a look but the nut arraingment is not on that page.
