79 300sd 617.950 how similar to 83 617.952

[rhodes2010]

Can I use a donor 1979 300SD Turbo motor in a 1983 300SD ?
The 79 lists 617.950 and the 83 says 617.952.

I can visually see that the vacuum pump is very different (even different from my 1980 and the 81).
Guessing I can switch in the newer vacuum pump.

Turbo looks the same, same location of alternator, AC compressor, Power steering pump.

So, does anyone think this engine is a good donor for any 1981 to 1984 Turbo engine ?

Thanks for all your help.
