Quick update.
This was the magic combination of extensions that worked perfectly to remove the two E12 bolts holding the starter.
The blue are 2,4,6" 3/8 wobble impact extensions. The red is my 3/8 Impact flex joint. The yellow are 6,10" straight 3/8 extension.
The wobble allow the E12 to align perfectly with the bolt and curve around the transmission. The flex makes a distinct bend to get out of the tangle of the shifting cables and get a breaker bar or ratchet on it.
I didn't bother trying impact I know from experience the long train of extensions act like a torque stick limiting the torque to useless but once broken free feel free to use a drill to spin that sucker out.
The top bolt is a strickly by the feel but it's the only E12 directly above the one you can see from below.
