This is my first post to the forum as I was unable to find out the info by searching. I am working on my Dads 1972 450SL. It is apparently a European model that was brought into the US before MB started selling them here. It is also both of our first experience with MB.

The car was recently repainted, and both of the outside door handles no longer work. I took one of them off and found that the adjustable part that has a little hook on it to grab the latch mechanism is broken off. The rest of the door handle is good, and this piece comes off with a single screw so it is easy to replace, but I haven't been able to find the part anywhere? Anyone have any ideas? It appears to be made of Pot metal, so it can't just be welded. If my description isn't clear, I could get a pic.

Secondly, I have absolutely no idea how the climate controls are suppose to work. It has 4 vertical levers (2 on each side) and then a couple knobs, none of which are labeled. One of the knobs appear to be the fan control, and one of them seems to control inside/outside air. Can anyone explain what the other levers are for?

Thanks in advance,
Mr_C

Levers 1 and 4 determine hot or cold. Hot up cold down.They also open or close the fresh air vents. They control the flaps on the left and right side of the heater box but in practice they should both be either up or down at the same time.When lever 1 is down it should close the hot water valve in the engine bay.
Lever 2 controls only the demister vent flaps behind the windshield.
Lever 3 controls the footwell flaps.
The face vents are controlled by the lever in the center dash.

I did a post explaining the adjustment of the levers- it's in the "sticky" section.

The switch with the 1 11 111 marks on it controls the fan speed
The one with the "swoosh" on it is aircon on/off and temp.

It is most likely a U.S. model '72. The VIN will help to answer that. 107.044 is a U.S. model 4.5 engine for 1972.

I think I know what part to are needing but a picture would confirm.

Thanks, I will check the VIN and see if I can find out more. Most places don't list a 450SL in 72, and it has things like euro bumpers on it, so I that seemed to confirm the oddity of it. I didn't realized they actually imported some in 1972.

Here is the pic of the broken part. I still haven't been able to find replacements, other than complete door handles on ebay.

I think all of them up to the 560SL used the W116 door handle. Try looking for a 73-80 450 SE, SEL or 300SD handle. Until recently you couldn't swing a dead cat without hitting one of these in a junkyard, but sadly , many are being repurposed by the Chinese.

Edit- looking at that, I am not sure that little dingus thats broken off isn't R107 specific. Don't buy a used handle until you find out.

Edit2: I'll bet you can make something out of a bracket that will serve the purpose. That pot metal can't be very strong anyway

It is not available as a part. I will look at some spare handles I have to see if there is a good one.
The confusion on the 1972 107.044 is that only the U.S. received them. They were originally badged and titled as 350SLs. Properly it is a 1972 350SL 4.5L. They were sold in the U.S. beginning late 1971. The rest of the world received a 350SL with 3.5L engine. They are 107.043 models.
There are two distinct signs of a U.S. model. 1. It has four round headlights. 2. The front and rear bumpers have two vertical bumper guards. The Euros have rectangular headlights and no bumper guards. There are other ways to confirm but this should help.

The have a 107 part number. That indicates to me that they are 107 specific. Mechanism may be similar though.

I think I am going to try some JB weld and see if that will hold. I checked and it doesn't take much force. I suspect these were broken when they were put back in after the paint job.

I also verified that the vin number is 107.044 12 04887. It also has the 4 round headlights and the proper US bumpers. Thanks for straightening me out on that.

I am begining to understand the confusion with the 72 450SL, what I find wierd is that no parts stores seem to know it exists, but I guess maybe I need to look it up as a 350SL.

JB Weld might well work in this application, but you can give it a better shot by grinding the chrome back near the break and using some gussets ( I like beer cans!) on both sides of the thing. Just putting the epoxy in the break concentrates the force in that one small area.

Hope it works for you. If it does, you will no doubt save a hundred bucks or so that can be used for the inevitable repair that can't be fixed with epoxy (like your flex discs)

The broken part was originally 13.5 MM from the back of piece. Let us know how the JB works out.
