I think all you can find these days are expansion valves labeled R-134a. They look exactly like the R-12 ex. valve, just have a sticker on the side stating R-134a compatibility. My understanding is the newer valves work fine with R-12. I have an R-134a valve in my 124 with R-406a and it cools great. I'd worry more about getting all four connections to seal tightly than whether it's labelled R-12 or R-134a.
