PART SEARCH W124 CONVERTIBLE

I own a Mercedes W124 E320 convertible and I am revamping the chassis. I discovered a rusted part I want to change. Unfortunately MB does not provide it any longer.

On this drawing the part is n°145.
(Golden part on this picture. This is NOT my car, it comes from one of a friend which is in great shape!)
The part, named BRACKET, has reference number: A1245458140 or A1245455047. It is a metallic bar that is screwed on the rear part of the rear sub frame. On both its ends are fixed plastic clips that are holding electrical wires (probably ASR or ABS). It is about 15 inches long and 2 inches high.
Can someone help me to find this part/piece?
Many thanks in advance.
Have a great day.

I contacted MB and they told me that, even if the parts seem to still be for sale in the official site, the parts are not available anymore around... the "world". So I called other official MB dealers in foreign countries (I speak French and a little German) and I got the same answer: "sorry not available any longer".
This is the reason why I am looking for a used one in good shape. I just hope somone knows where to find one.
Part N°150 is also the plastic clips that are still available and that I already purchased.
I hope I posted this subject in the right forum. If not tell me.
So many thanks for any track someone could send me. Regards.

My car has 124k miles but comes from NY and was sold in Florida by its first owner. I suppose the winter salt in NY + the sea salt in Florida might have done the "job"! But the rest of the rear sub frame is really in good shape with only minor surface rust. The car is actually in the hands of of the coach builder for 2 small holes and he told me that the understructure was in a rather great condition.
The car has been through exhaustive inspection during the administrative importation process (obligatory over here, to get a valid title!!!) and it behaves remarkably well for such an "old" car, including a total absence of natural tendency to pull to the right (or the left) as many W124 do. I really don't know why this piece is in such bad condition. My only explanation is that it my may have been switched with one from another car in bad condition before the sale... who knows???? The rear suspension handles very fine even when we are 4 in the car (thanks also to the ASR too). I just encounter some "klonks" in the front train at low speed on uneven roads. They probably come from dead springs rubber pads. They will soon be changed too.
Merci à vous uvr708!

The problem, as you advised is that there is no stock at any USA MB dealer and in Germany-----however the part is still good and not discontinued therefore can be ordered.
Send me sixty one bucks and I will order the part for you. Remember that price will be the ex works Florida USA price---you still must pay all forward shipping, taxes and duties---advise!!

I even called the official French "Antic&Classic Mercedes" subsidiary" (MB department specialized in Old and Young timers) and they told me that they cannot do anything. Last year, they were able to pre order my cabriolet specific exhaust pipe line (incl catalyze) and ask for a re-manufacture of it (I waited 3 months). But for this (simple) part it is out of question!

Anyhow Plutoe, if you are certain to be able to get the part we can surely find a way to do it (Paypal or bank transfer...), as I have no real other choices to get it.
Just let me know in MP. No problem.
Plutoe, many many thanks in advance for your help!

To answer uvr708, this morning I just saw the "piece" on a W124 Station Wagon E320 with... ASR! I tend to think that this part is probably mounted on W124 cars with ASR (anti-skid) system. The part was corroded but much less than mine, and the car is from Paris origin, meaning neither very cold nor heavily salted...
So, in conclusion, this part is not only dedicated to the cabriolet!

2. Our cars have a similar history (NY & FL) and sound like they are comparable. (That factory paint from the 90s is remarkably strong.) The equivalent piece in the rear suspension on my Cabriolet is not rusted, but there is superficial rust in other places. (The front tow hook was ugly.) Can you tell me the particular spots where yours needed attention? You mentioned two holes. I'm about to clean up my undercarriage as well and I'd like to know if I can learn from your recent work.

URV708 hello and sorry for this very late answer to your post I did not see. The 2 rust holes were located on the left side under the left side of the driver seat. With a screwdriver you can gently hit the chassis to see if you encounter "soft" parts, which is a good indication of rust presence. If the screwdriver makes a hole it is even clearer.
You may also find rust:
- under the spare wheel compartment,
- behind the rear wheel around the water evacuation holes,
- in the wheel compartment around the round rubber seals,
- just behind the front wheels: if you take of the wings plastic covers and the long plastic trims going from under the front wings, under the doors up to the rear wings, you will be able to see the possible damages,
- around the upper attach point of the shock absorbers (front and rear),
- under the windshield washing reservoir on the right part of the engine compartment (most of w124 do have rust there),
- more rarely, all the attach points of the rear cradle.
The best of course is to have access to a lift and with a powerful light to be able to carry a full inspection of the chassis.
My advice would be to treat ASAP all small rusting problems before they become big!
This is also what we discovered after the holes in the chassis. Left rear wheel compartment. All was taken off and welded with new MB parts. New blackson and new paint.
Before: left chassis side.
After: left chassis side.
Right side clean and treated.
