Would this include a new compressor?

r134 compatible seals and oil is the real issue with the conversion, so one does not change every component, including the compressor. Thorough flushing is critical, and always a new receiver/dryer of course.

No "they" don't.

With my experience with a converted TE done by the PO, I would make all efforts to stay with r12. The wagon is like a green house, and IMHO the MB A/C system is woefully undersized for double the load of a sedan.
Also, replace all of the vacuum control pods while the dash is out and the heater box open. I used the all aluminum ACM evaporator when I replaced one, and not the MB copper/aluminum part.
