Hi K
Hard to make out the print on the diagram, it's #86 3/8" whit x 11/2" grub screw and #94 3/8" whit lock nut, there should be 2 off each, however I only have the one. see photo, they are unique as in only being 2 off on the saw. In your picture, It looks like there's one just/right behind your riving knife trapping bolt, It does not show the riving knife schematics on the AGS 10 diagram, though It does on the 12 diagram and is #100 riving knife trapping bolt,
Kind regards
Rob
