I have the 21-2201HP on my W108 4.5 I changed all the barrier hoses and flushed the system. Went with R134a. It cooled OK until 2 years ago when I bit the bullet and changed out the condenser for a modern horizontal flow aluminum one. Now, I get cold in the car and never have to run at the coldest settings, even in 90 weather in traffic ( It takes me an hour to drive the 8 miles home in the afternoon). So, I'm with "okyoureabeast" on liking the R-134a. You just can't expect it to perform with the antiquated condenser.
