Dean,
Disassembly of at least the reverse rod should be done. The most difficult
issue with this is removal of the small square headed tapered bolt / pin. It
can easily be broken. I'd recommend getting an 8 point socket that fits it
tightly and don't apply any sidewise force when loosening the bolt. A firm
initial rotation should get it started.
Locate. Drill and tap the isolator switch hole.
Assembly of the rod is pretty straight forward but you have to make certain
you get the little ball inserted properly. The ball keeps you from engaging
it's rod incorrectly. There is also a cap, spring and pin that helps lock
the rod in place when you shift. Count the turns of the cap when you remove
it and replace with the same number of turns making certain it's at least
flush with the sealing surface of the top cover. All of the disassembly and
reassembly is well covered in the factory service manual.
Hope this helps, write to me with any additional questions.
I have the tap if you'd care to borrow it when the time comes. Don't know
the drill size but can look it up based on the tap size. I don't have the
drill, my shop did.

Thanks, Jerry. Is the disassembly of the cover very involved? It looks like
at least one of the shift rods needs to be removed prior to drilling.
