Well i tried to send a PM don't see anything on my out box in messages
i may not be doing it right.
Anyway i removed my bad screw. Measuring both the tach and speedo
cable ends they are 15mm in dia.. The center point of the screw hole on the brake drum looks to be 10mm forward of the hole edge. the tach cable screw hole with the engine in the frame can't get to it to measure it with my caliper, but just eye balling it i would say its the same 10mm distance.
