The analogy to the ML7 - the screw would fit into a bracket on the face of the cross slide - you can see two bolt holes on the front face of the cross-slide, which would then interface to a brass nut inserted into the saddle (the bit that straddles the ways... which the tailstock sits on)

Have a look at https://www.myford.co.uk/acatalog/info%5f686%2ehtml for an example
