Yoke removal help

If you've got the nut off,, a coupla sharp raps with a small hammer should persuade it off..

I assumed ( I hate that word) that it had been broken while tightening,, my apology,, having sheared off it very likely could be binding on the threads..

The reverse drill bits are an excellent choice if you have access to one,, if easy outs won't bite.. -

This is not a "recommended service proceedure",, but you could use a hacksaw or similar to cut a slot right thru the yoke and screw, sufficient to get a screwdriver to bite,, then clean up the mating surfaces with a file,, the small saw mark in the yoke shouldn't affect performance....

hope it helps..
