Hi everyone!

I just paid $754 (plus install etc, etc...) for a genuine MB replacement A/C compreesor for my 86' 300E. How do I make sure that I recieved the part I paid for and not some aftermarket replacement? Are there any indications to look for on the compressor from looking at it installed under the hood?

Thank you to everyone for all your great contributions to this wonderful website!

Jerry
