I don't get you here Chuck. The hole is 7/16-14 threaded only maybe halfway and then the other half is where the clamp shoes (big pins with the one end angled) go. Parts 43 and 42 on the diagram. NES makes a tool that would work but it's around $60 IIRC. I just had an idea. I'm going to get a 3/8-14 so it matches the pitch but is smaller than 7/16 and maybe I can somehow get the first two threads going again by working the 3/8 tap out while pressing the tap against the wall/threads. :thinking:
