Correct. All R129 sway bars are the same so don't worry about the model. Use R129 bushings in all 4 positions. The only modification needed is to bend the sway bar hanger mounts to align with the bar. That means the hangers won't be perfectly vertical any more, but it doesn't matter. I've been happy with it on my car.
Thanks for quick and helpful replies guys!
Beater - found your thread. You made some nice looking brackets for the 55AMG rear bar!
Hopefully it will fit just as easy in my m113 w201 project car. As w124 v8 sway bars are hard to come by in Europe, r129 might just be the answer i was looking for, thanks!

Oh, interesting. Is the track width on the W201 the same as the W124? If not I could see the length of the bar potentially being an issue. Also, if you were considering an R129 rear bar I'd say skip that. The rear R129 sway bars are tiny. I actually installed a 400E rear bar in my R129 as an upgrade.
Apart from the fact that the W201 is a narrower car with suspension pickup points positioned closer together, the W201 and W124 platforms are largely similar. Most components are interchangeable.
As far as I know, the main exceptions are the steering arms, tie rods, steering damper(?), rear subframe, half-shafts, and rear sway bar.
That said, front sway bars from the W124 can be fitted to the W201 chassis. To make them work, you simply need to trim about 1.5 cm off each end of the bar. However, it’s important to match the sway bar to the engine layout. A 4-cylinder sway bar won’t clear a 6-cylinder oil pan, and a 6-cylinder bar will interfere with a V8 oil pan.
Rear sway bars are unique for the w201 but are interchangeable across all W201 models. For example, I’m currently running a W124 300E front sway bar and an EVO2 rear sway bar on my 190E 2.6.
Interestingly, there are now a few aftermarket sway bar options available for the W201—both front and rear—for 4-, 5-, and 6-cylinder versions. In contrast, aftermarket support for the W124 seems to be limited.
Since I’m planning a V8 swap, I’ve been specifically looking for a W124 V8 sway bar, as there’s no aftermarket alternative that fits the application properly.

That makes sense. I believe you would have to trim the ends to make it work, but otherwise it will probably fit. Let us know if you're able to make it work. The only way we gather collective community knowledge is by trying stuff and sharing our results.
WOW - and they didn't break? I think these are made of spring steel because they are constantly moving back & forth a little bit during driving when the suspension is loaded/unloaded. Spring steel can be bent a bit giving a permanent change yes, but not much and not too sharp bends!! @Beater400E, I guess you were within the narrow limits then!
They are definitely not spring steel. They're just stamped mild steel. As long as the movement doesn't exceed the elastic limit of the mild steel, spring steel is not needed. They can be bent by hand, no problem. I've been running it that way for a year or two and haven't had any problems.
OK, learning as I walk. Many thanks, and good to know.
