Steve, I also have not worked on an SD but did change the starter on my '84 300D a couple years ago and my experience was very similar to that elucidated by J. Friesen as my extensions reached back to about the center of the driveshaft in order to get proper fit and torque with a breaker bar. I had also tried a stubby 10mm and reaching from above, but there was no way to get enough torque in the confined space to break things loose. Once these two allen head bolts are disconnected you can remove the starter from below when you've previously turned the steering wheel all the way to the right to avoid things. Good luck, my garage got quite "colorful" when I did this job.
