OK. I guess that I am too used to dealing with Clausing where, if they no longer stock the part, they almost always have the original drawings (at least for the lathes - less so for the mills and shapers).
In that case, the first thing to do would be to check the angle on the tip of the Nylon Patch or Nylon Rod gib screws that he was sent. Be sure that it is the same as on the spotting drill and that the spotting drill just fits through the tapped gib screw holes in the side of the cross slide.
I would suggest acquiring a roll of 0.005" and 0.010" shim stock and cutting enough strips to approximately center up the gib top to bottom in the slot that it fits into. Shim both below and above the gib. Use three round nose set screws to lock the gib immobile in the slot. Spot drill the first hole, move one of the screws to that hole and drill the second one, and so on. Then move the gib to the drill press and use a drill bit the diameter of a body drill for the screws and with the same included angle on the cutting end to enlarge the spot drilled hole to the diameter of the screws. Use a depth stop to get all four holes to the same depth which, absent instructions to use something else, I would make around the depth for the body drill to be cutting to the full diameter.
To pre-position the gib vertically for getting the gib screws into place, I would use the shim pack that was under the bottom of the gib for step one above.
