Hi
I am trying to restore the A/C on my father-in-laws 1984 300D Euro. The A/C is after market, i have got a compressor and am now trying to get the Expansion Valve and receiver-dryer.Was there one type off kit used on Mercedes or was it just a slap together. I am having a hard time finding these items, the Receiver-dryer is a Parker # 4-4047 and the Expansion valve is a Parker 329-006
Anybody ever dealt with this after market system.

Thanks
