Whip stuck in shaft

heat ? If you ever get it out might not hurt to put a little anti sieze on the new one.

 

If it wasn’t bottomed out you’d have a better chance, but I would still try driving it down, then twist and pull up.

 

channel locks will just slip, vice grips will lock down on it

i'd try spraying PB Blaster from the top of the mount, then some into the set screw?

then as for the replacement, maybe as suggested anti-seize or even di-electric grease?

 

treat it like a broken exhaust stud. weld a nut to it and twist it out "lol"

 

Vice Grips locked down tight. Then tap it up from the bottom ?

 

You can try unscrewing the top section off the coil...stick it in a vise to hold it, then take something and try to knock it out from the bottom...Worst one I had, I finally got lose just squirting some penetrating oil at the top where the stinger go's in, then after a hour or so I used some pliers and vice-grips, and just wiggled the stinger back and forth while pulling up....finally came out.

 

Also run a strip of that black tar like tape,coax protector around any connections..
