ignition barrel studs

[grumpyfrog]

I know a few of you have done some replacements this year, so with removing the studs, do they need drilled out, or do they eventually screw out if I cut a slot in them? If so are they normally threaded?

once you drill the heads off they unscrew as normal with the help of a pair of mole grips

Or do as I did... fail at all the correct bolt removal methods... use an angle grinder and chop your yoke up and use it as a fork brace!
