1992-1993 W124 Hirschmann antenna grommets - where to buy?

[gsxr]

NOTE: This post is referring to 1988-1995 models with the angled antenna. 1986-1987 models with vertical antenna use different grommets (external portion is shorter).


Apparently the W124 antennas on 1992-1993 models only have a different mounting arrangement and grommet, compared to the 90-91 and 94-95 design. The 92-93 has a metal locknut on top of the plastic/rubber grommet and a thin plastic seal that goes against the paint. The portion under the fender is a metal piece that slides onto the antenna (not plastic/rubber).

Mercedes apparently only sells the 92-93 grommets as part of a higher level assembly for $74 list (124-820-56-75), which is crazy when all I need is $5 worth of grommets. The Mercedes part number on the large grommet I need is 124-823-03-30 with Hirschmann (?) number 722-861. For the thin plastic seal, there is no Mercedes number, but it has Hirschmann number 722-410.


Does anyone know where I could buy these 92-93 grommets separately? I've searched via Google and all I can find are the wrong parts, everyone is selling the 90-91 and 94-95 grommets, which do not work... these are MB numbers 124-827-07-98 and 124-827-08-98. The lower section (124-827-07-98) will not physically fit on the 92-93 antenna.

UPDATE: The early 94 models also used the funky 92-93 grommets... the change occurred in early/mid 1994 production. The EPC says the chassis break point was C083747 / C083748.
