Guys,
I'm having the same issue with my 87 260E. Seems like no one seems to carry the R12 anymore. and if it's a known issue that the R134a wont cut it for these systems then why isn't mercedes making it available for the older models that were meant to use the R12 ? What should one do in a situation like this because I've been told that the R12 is too expensive and that's why everyone just stopped keeping it...
