Have you done this? Do you know someone that has? I know someone who has all the parts needed to do the swap, except the drive shaft. It appears that a drive shaft from a w126 long wheel base would work. The 240D manual tranny is 6 inchs shorter that the automatic from the w126 300SD. My questions are:

1) What problems did you run into?
2) What did you do for a drive shaft?
3) How successful has the conversion been?
4) Would you do it again?
5) What else do I need to look out for?

My car is the '83 300SD. Donner was a 240D with ~150,000 miles on it.

Thanks for the help.
