That was me with the 6 hour job on a LW300 :-((

Hopefully for you there is more room and better access for you. My major
hang-up was that the nut holding the battery cable to the starter solenoid
was stripped at the threads (from loosening and then arcing - burned off all
the threads). Couldn't even loosen the battery cable since everything is
bundled and even harder to get at. Having a 3" diameter mirror saved the day
since I couldn't see directly. The L series also uses inverse (male) Torx
bolts in a lot of places, the starter included. Don't know if they are used
on any other models (L-Series was designed by Opel in Germany). If you need
a set, Lisle has them - available at most auto parts.
