Rear window telephone antenna base — a genuine BMW part, number 84 50 8 375 135. The number stamped on the part is 84508375135; BMW's catalog files it under the short number 8375135. You will find it on our Instruments & Electronics shelf, under Antenna.
It fits the E36 sedan, coupe and touring (318i, 320i, 323i, 325i, 328i and M3, 1992–1999), with the M40, M42, M43, M44, M50 or M52 and other engines — and the European-market versions.
BMW draws it on 5 diagrams, among them Retrofit kit, window antenna (03_3105) and Retrofit kit, window antenna (03_3106). It weighs about 35 g (under 0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
