Has anyone "updated" their older w123 with a newer transmission?

I am loathe to continue troubleshooting my current transmission aggravations with my 1980 TD (vacuum-only control trans). I have access to a reasonably-priced replacement from an '82, which will come with linkages and a usable Bowden cable.

Has anyone done this "conversion"? Or is there an existing thread you can point me toward?

Right off the bat I would imagine I am dealing with:

- changing the speedo
- needing a different vacuum control valve
- revising the vacuum setup
- different front driveshaft?

Thanks in advance, etc.
