I tossed a PF condenser in the 300SD as the original sprung a leak due to an unruly rock. My SD came with the small tube unit as found on the '85-87/90-91 Diesel W126. Trying to find a replacement was a waste of time, so now I have R12 with a PF condenser. I would agree it would be a requirement for the early condenser with small aux fan cars to attempt to run 134A.
