Pin — a genuine BMW part, number 52 20 8 135 753. The number stamped on the part is 52208135753; BMW's catalog files it under the short number 8135753. You will find it on our Interior Body shelf, under Seatbelts.
It fits the E36 sedan (318i, 320i and 325i, 1992–1998), with the M40, M42, M43, M50 or M52 engines — and the European-market versions.
BMW draws it on the Seat, rear, cushion, & cover, basic seat (52_0533) diagram. BMW's catalog calls for two of these at each place it is fitted. It weighs about 1 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.
