You can swap your input flange onto any W124 diff but you will need a special 12 point 30mm (i think) socket.
The second limitation is the differential ratio. You have a 2.64 differential and most of the gasoline diffs are much shorter (aka higher numerical ratio). If you were to use that 300te (2.87) diff which would give you better acceleration at the expense of more noise on the highway. The differential and speedometer are also paired so you would also have to chance the speedo in order to keep it accurate.

Scroll down to W124. Going from 2.64 (300td) to 2.87 (300te) is not a huge difference and you might enjoy the improved acceleration. I would go for it. Don't forget to also swap the speedometer.

That's exactly the info I needed - and was also dreading. Seems I really need to find a 300D differential - I have a 50 mile one-way commute everyday on I95 - so being able to spend quiet time at 75mph is important to me. Guess I'll post in the Parts Wanted section should I find out that I need a differential. I'm not feeling like rebuilding a diff.
Thank you again !
