I drilled and tapped a 1/4 20 hole in the end of a 1/2 in stainless rod then milled a flat spot and drilled a hole through to take the cutter
Not sure if this is the best way but i dont have invalute cutters yet
Not perfect but seems to turn on the lead screw nicely

Do you have a set of plans or drawing showing how to time this threading indicator?

What is the tpi of the myford leadscrew? My Southbend is 8tpi. If yours is the same I can find the instructions. The SB uses a 32 tooth gear but conceptually they would work with a 16 tooth gear.
