No one seems to carry #2 machine screws longer then 1 inch and as you can see from the first pic, I needed at least 1 1/4". So, I put the original rivets back in and inserted light gauge copper wire through them, pulled it tight, crimped it with slip-joint pliers and soldered each end. It's now reinstalled and working perfect. Except, of course, I can't find the two small bolts that hold the panel under the dash in place (which I never even needed to remove). Two steps forward, one back. By the way, has anyone seen the device in the last pic? I've been led to believe it's some sort of alarm system so, unlike all the unconnected stereo, amplifier and graphic equalizers I've removed from under the dash, I'm leaving this alone.

Great McGyver awesome fix!

Never seen that alarm panel before. It looks like an after market unit.

Ripe for removal.

Blower is now working great but the "it just needed a refill with R134" (I knew that was too good to be true) fix by the dealer failed after 1/2 hour of use. There is obvious leaking around one of the elbows (not sure if it's hi or low pressure) that are mounted to the top of the compressor. Since this is a Euro car with manual A/C, the compressor seems to be different than the 450 & 560 SLs use. Mine has no visible name plate to identify it but, surprisingly, I just saw a picture of a 70's AMC Ambassador V8 engine and it had the identical compressor, mounted horizontally instead of vertically like mine.

Does anyone Know the brand and maybe the model of the compressor? Is there a source for these like the compressors for the US models? Are there rebuild kits for these? It looks like its probably just an O-ring or gasket at that joint but if one is bad, the rest probably are too. I know the dealer is going to quote me $$$ on the part "they have to order from Germany" like they did on the switch for the blower. Attached below are pics of my compressor and the AMC version.

That is a York/Tecumseh 210 style compressor. Used on FoMoCo AMC and Mopar for two decades. Any competent parts store can sell you one, new or reman with a serial number. Should be a serial number plate or stamped serial numbers on it somewhere. If not take them the dead unit they can measure and match the port and clutch configuration.
