Hi Kebreda.
Do you have internal halyards?
I you want frustration and a waste if time,
climb to the top of the mast.
tie a fishing sinker to a strong line and lower it from the top.
It will jamb and wrap around everything in the mast including tiny rivets.
If you want to actually get the job done get an electrician's snake,
You will still need to go up the mast.
Feed it down, connect the wiring and haul up.
