The starter is real hard to get off, but you don't have to
cut the frame

or anything, it is just hard to wiggle
it out. And it is hard to put it back on too, kind of like
the alternator.
The hot wire to the starter has a doubled set of
nuts on the post, locked together. They're low profile
nuts, you can't hold the bottom one with a regular-thickness
wrench. The post is really just a bolt, the head is held
in a plastic slot inside the starter. I didn't have a low
profile wrench, so I tried to turn just the top lock nut.
The bolt-head spun in the slot, and broke the plastic
part inside the starter. This particular plastic part has
no part number on the fiche, you can't buy it.
Get a low profile wrench to hold the bottom nut,
and then loosen the top nut.
