Needing to replace the antenna seals on my 1990 300E 4Matic, I was able to read the part number of the lower (inside) seal (124 827 07 987). While my local MB dealer still had this seal in stock, and they are still available, I was told that the matching upper (outside) seal (124 827 08 987) is NLA anywhere. I verified this by calling MB Classic in California, and via the internet (Autohaus, Pelican, Mercedes Source, and a few others).

While still scrolling through pages of MB seal images, hoping to find one, I came across an image of a R129 lower seal. This seal looked exactly like mine. Enlarging the pic, I was able to confirm that both lower seals were the same, despite the R129 seal's having a different part number.

I immediately looked for, and found the part number for what would be the matching R129 upper seal (129 827 02 98). My MB dealer had one in stock, so I immediately headed over in order to test, and confirm their fit. They fit to the point that they even made a slight snapping sound as they seated themselves together. The upper seal fits well against the outside quarter panel as well.

So, for anyone whose 124 uses lower antenna seal 124 827 07 987, an R129 upper seal 129 827 02 98 will work

Good idea, Andy, especially since more parts will likely become NLA, resulting in our having to find substitutes. The topic of NLA parts at the Tech Session came to mind as I was trying to figure out options to my NLA dilemma.

plinker, the "NLA" 124 827 08 98 upper seal in your pic looks exactly the same as the R129 seal that I used. I have to think that they actually the same seals, except for part numbers, which would explain why the R129 seal was a perfect fit with the 124 lower seal. It would be nice if MB would cross-reference them

It stands to reason that if (or when) 124 lower seals (124 827 07 98) become extinct, R129 lower seals (129 827 03 98) will be perfect replacements.

Here is a pic of the R129 upper seal (129 827 02 98) installed with the W124 lower seal (124 827 07 98[7]):

Yes, they are different.
The car/slope is a more extreme angle there. Something was wrong with this car's, so I robbed the old one off my other TE. I had to use silicone to make the seal work against the car. The rear side windows leak anyway, so there's always some moisture in the rear storage wells after a good rain. It's good thing I live in a semi-arid climate. The real leak monger is the hatch seal if you don't keep it clean inside the track. What a surprise when you pop up the rear seat and everything is drenched. It took over a yr for this car to not smell like musty leather Seattle. The PO had the pop up seat out of the car and was surprised that I wanted it when I bought the car. The seal track was absolutely embedded with Seattle grime. So far, no water on the seat at least.

Al the same see picture .
They are different. I had to return both seals in your third pic to my dealer (124 827 06 98), as the lower seal was too narrow. There was a gap on along both sides of the seal, between it, and the outer edge of the quarter panel bore. The correct lower seal for me was the one in your first pic (124 827 07 98[7]), and it's corresponding upper seal (now 129 827 02 98). The corresponding upper seal in your third pic did not fit completely over the top of my correct lower seal.

"07"'s circumference is wider overall, and it's "flutes" (if that's the right word) are more pronounced than "06".

Yup! For those who weren't there ;) Dave and I sat in on a Mercedes club Tech Session at one of the local dealers. There was a club member there who couldn't stop praising and touting Mercedes and the Classics Center specifically. It was as if he personally was the Classics Center's best customer (which he is not). It was nauseating for me. I brought up a few critical parts that recently were not available - Catalytic convertors for a W210 and tank-to-fuel pump formed hose for W124 TEs - and how little MBNA and the Classics Center did to help (didn't even return my phone call). I finished by mentioning I thought the Classics Center was more dedicated to Gullwings and SLs than anything else. One of the dealer reps (a German accented guy) jokingly responded that I should get used to using Amazon. The folks leading the meeting said they wanted to have Regional Reps attend a future session. In the meantime, and more realistically for the longterm, we need a DIY thread that captures all the effort Benzworld members put into alternative sources for NLA parts.

plinker, thank you for the information. Since the installation of the combined upper, and lower seals went so well, I will not be needing to make any changes.

124 coupe/sedans used at least 3 different antenna angles over the years, with the later years more sloped back than the earlier years. I think the transitions corresponded with the side cladding changes.

ah,m found this in the FSM... http://freescruz.com/.priv/W124/w124CD2/Program/Chassis/82-8105.pdf

"From the start pf production, the antenna inclination is approximately 10 deg. for the sdan, and approx. 30 deg. for the coupe. The antenna inclination has changed twice for the sedan. As of 02/87, approx 20 deg for the mechanical antenna only, as of 09/88 approx. 30 deg."

other interesting notes of improving the ground plane, first on the V8's, then in 7/93 all 1240s, this was done via a foil sticker inside where the antenna goes through the body.

also the hole size changes for the 30 deg. antennas.

since we no longer need analog cellular phone antennas, the Hirschmann 'generic' replacement antennas come with their own rubber mast things, and worse case you relocate the motor using the supplied mounting strip

It was interesting to scroll through the antenna evolution. Thanks for the link.

Interestingly, my '88 and '89 had two different antenna angles so I'm not sure about the '87 change over.

Good point. There are times when hard start/end dates are not completely accurate. Based on the number of 124 antenna seal part number variants that I came across, I'm just glad that there was enough of my old lower seal left for me to be able to read it's part number. Otherwise it would have been a guessing game trying to determine the correct seal for my car.
