BenzMac,
Which model years constitute the "early" ones (which do not convert well), as opposed to which later years that do convert well? I have a '88 W124 and W201, and a '90 W124 -- they all have good A/C systems right now, but down the road I'm sure they'll need servicing and/or freon substitution.
Thank you.
