seat compatibility for W115 (1976 300D)

i also posted this in the W123 board. sorry for the double post, just trying to catch someone's eye. apologies out of the way, now we can start.


the seats in my 1976 300D (W115) are coming apart from the inside. i believe this is a common issue for these seats—the horse hair (or whatever it is) is disintegrating and piling up in the form of disgusting dust and chips all over the carpet.

i figure the least costly thing to do is just replace the entire seat rather than re-upholster my existing ones. problem is, whatever seats fit my car exactly by year, will be just as old and likely to disintegrate as the ones i already have. so i'm wondering what other mercedes seats might be compatible. could someone here clue me in as to possibly other mercedeses from the 80s-90s that i can hunt down for their seats? (ie, cars that i'm likely to find at pick-your-part or other wreckage joints.)

i'm mainly looking for the 2 fronts, manual (if there were electric options i don't have them), just looking for something that will line up seat-to-track with the chassis of my car. authenticity of vintage/model is not an issue.

please tell me either by model/year or by chassis number.

Not necessarily. If the outside MB-Tex is intact, the replacement of the stuffing is actually not that expensive.

It's also not difficult at all. It's easiest with the seats taken out of the car. Removing the back from the seat portion is easy once out too. After the parts are in pieces, you can compress the seat springs and tie them in that state with string or wire. The covers come right off.

The pads are available online (I bought a full set for my 108)

After removing the remaining horsehair pads, you can replace the stuff with layers of blankets (I sheepishly admit doing this with my 114). I used a worn out sleeping bag and the blankets from my childhood my mother was convinced a 33 year old would still need.

I hand stitched the pieces together to make a nice fluffy but firm pad, and used fishing line to fasten them to the seat frame, to prevent everything from sliding or bunching.

I then replaced the seat skins and removed the string keeping the springs compressed.

Total project time, including prep and seat removal/reinstallation: about 4 hours.

I was talking to a friend of mine about how the horsehair pads seemed a bit expensive. After explaining what they were, he suggested getting some 'Sweat blankets' for putting under a horses' saddle, and trimming them to fit. I've not had the opportunity to investigate that further, but a trip to a tack shop might be worthwhile. Especially if you have an acquaintance that is familiar with horses.

Just a suggestion.

Remember: It's not just a car. It's an Adventure.

I just replaced the driver seat that was doing the same thing in my 1975 240D, I used a seat from the passenger side of a 1983 300sd, the seat track was the same width but the length was longer and I had to use other holes on the rear end of the track. The seat was also an electric seat which I was able to wire up but the switches are just dangling beside the seat for now until I find a way to mount them to the side of the seat. I know it doesn't match the other seat but it sits nice.
