Well yes if there's nothing wrong with your origional cages, but then if your MB is over 20 years old wear, tear and age will sometimes warrant replacement. Bad cages and definitely bad blades and damage your windshield.

When I went to autozone, the salesman pulled out a box of adapters and found the ones listed as MERCEDES. These little babies made the hooks on my 300SD work perfectly for the aftermarket anco blades and bodies. I have had no problems

I have seen all current production brands, and tried to mount them to a 1985 300SD, none fit or hold correctly.
Perhaps the previous owner changed the motor arms on your W126.
I have seen brute force, glue, epoxy, zip ties and screws used to mount the current production brands of after market wipers.
Please post pictures, like the reference pictures in my last post on this thread.

The refills are known to me, only the blade/arm is of interest.
Note:
I would like to know how and why they fit, a brand and part number would really help.

Whunter, I reviewed the pictures and am not sure what they show. I had real trouble with the adapters that came with my new "Silblade" wipers getting it to fit my SDL. I finally gave up and was able to successfully transfer the connector (adapters) from the old blades to the new ones. Those adapters have this sort of hinged locking mechanism. I guess I still am not sure about the difference between a left and right wiper. Mine seem to be just fine being identical.

Strange, but both of my other MB's were no problem at all.

By the way, do all 126's have those "coves" (leaf and snow collection caves) that the wipers hide in? I just realized what a real PIA that is now that fall is over here in the mid atlantic. I spent an hour last weekend cleaning out all of the leaves and debris that collects down in the back of the engine compartment.

Tell me about it... whunter went with me to pick up a 300SD last year. While going over the car he tells me about the leaf collector and how fires have been started from the leaves collecting by the blower motor resistor box.

Not more than two or three days later I'm driving my new 300SD down Telegraph and what do I see? Smoke coming from under the hood. The d*** leaves are on fire! I pull over, pore water down the leaf collector and then proceed to scoop out a pile of leaves. (good thing I have small hands)

I bought bosch blades from pep boys and they clipped right into the wiper arms. That was several months ago and no problems. Perhaps someone changed the wiper arms.

Does it have these tabs?

It doesn't have the tabs. It has a locking mechanism that snaps down in the area of the green arrow. I will try to post a pic later.

When I bought my '86 SDL in May '04 I did not realize it had bad wipers. I was picking it up at night and just did not see them. I was driving from OKC to Cincy and did half the driving that night. It rained about half the trip. Fortunately, somebody had coated the windshield with Rainx so I was able to see. I went to an Autozoo and tried to buy blades. They came out with their box of adapters and tried every one that was even close. None of them did the job. I just drove home and ordered new left and right blades from Caliber. Now I guess I need to get another set of refills (already replaced them once). Wiper blade rubber doesn't last very long in Cincinnati. Sounds like there may be a difference between earlier 126s and '86 up models in the arms.

I bought a set of Bosch blades and cages from Autozone for the SD, the best ones they had they were like $18 each. They worked fine for a month but since they lacked those tabs both of them popped off. Lucky the passangers popped off in the parking garage at school and about a week later the drivers side popped off in my driveway. It would have probably caused damage to my windsheild or wiper system if I couldn't pull over or shut them down right away. Because the cage kind of flips vertical and jams one arm.

I pulled the wipers off the SDL, they are the proper ones with the tabs and stuck them on the SD. I'll buy the SDL a new set in the spring.

Here's how they go on. The plastic cover lifts up and snaps down against the hook end of the wiper arm. Not sure how it applies to other years.

I just recently got the Bosh blade refills from my stealer, they were $4 less for the set there than on fastlane. I paid $18.03 for both. Took about 6 mins to install them, they work great, no more streaks or hazing. The cages that hold them look as if they could last forever...they're very sturdy. $18 every 2-3 years is fine with me for getting good bosch blades.

The prev owner of our 83 tried to buy off brand replacements for it, the right one came off while we was driving, so he broke down and bought the OEM set for $60. He said it always felt "loose" when he tried to clip in the aftermarket ones, but OEM went in solid and good. As for me, I'll stick with OEM on stuff that lets me see where I am going.

Time for me to get some bosch cages and wipers. I sitll have the origional ones off my car (bosch) but the cages are pretty worn out. I put on some blade deals from napa and they worked for awhile. But now I can't see for crap so I think I'll drop the 60 bucks *tear* on new blades and such.

Course my windshield is pretty old

What do those tabs actually do? Are they just a release mechanism, or do they serve some stability purpose?
