Hello Everybody,

This is not related to MBs, but i wanted to know from techs and DIYs.

On my 1974 RR silver shadow, it has R12. The AC works but is low on freon and i need to make a decision:

1) Stick to R12
2) change it to R134a
3) change to R12a

I am not familar with R12a, has anybody here used it before on any car?

How does it work?
