Fittings are in different spots between the V8s, I6 gas, and Diesel.
NO W126 ever had a parallel flow condenser from the factory.
The performance in my cars is more than adequate when I am in Houston on R12, which is extremely humid and quite hot in the summer also. Even in Houston when my 560 was on 134A it cooled decent around town and far better down the road, but that is to be expected. If you cannot get out of the upper 60s for vent temps on 134A in a V8, you have other issues.
Why people try to save a few dollars by using 134A versus R12 is beyond me. Buying three cans of R134A for ~$40 at Wallymart versus ~$100 for four 12oz cans of R12 on Craigslist to save $60 but reduce cooling in a volatile climate seems like false economy.

84-85 gassers have the better condenser as well. Both of the condensers I have were salvaged from 420SELs. The main difference is the smaller tubes and more parallel runs. The older condenser has something like 12 runs while the upgraded condenser has something like 16 runs. I counted them once but forget the exact numbers. In effect, the surface area is increased in the later condenser. Upgrade the fan as well or your cooling at idle will be poor.
