Hi Phil,
Look forward to seeing your setup too.
Slight correction to my previous post:
I think I probably drilled the broken stud with a 5/16" drill not a 3/16" drill as the Ford blocks are tapped 7/16-14 UNC. that would allow enough "meat" to prevent hitting the crest of the internal threads during drilling even if slightly off centre. It also kept the junior hacksaw blade more rigid from having to be ground too narrow for the hole.
Probably best to start with a smaller drill and see how it is positioned before going to either a 1/4" or 5/16" drill. Main thing is not to drill so much that there is only the remains of the stud left it the internal threads. Then you will have problems cleaning them out.
I did that once on another part with a broken stud and it was a disaster.
Cheers,
