That question I asked my self in case of a starter failure. Well, two possibilities:
one-- I make a hatch and squeeze myself into the foot box, may I ask a smaller person to do that and change it out.
or
two-- I buy a new starter and if the starter fails in the future I have to lift the engine off the motor mounts and change it that way.
The donor starter worked just fine for the last 12 years. Close to 100K on the clock means about 4000 starts (daily driver). If the new one holds just the half of it, by that time I'm 85 years old and have forgotten why I came in the garage in the first place...
...I choose number two.
