Spiral spring, top right — a genuine BMW part, number 52 10 7 129 250. The number stamped on the part is 52107129250; BMW's catalog files it under the short number 7129250. You will find it on our Interior Body shelf, under Tail trim.
BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.
BMW draws it on the Seat, front, backrest frame (52_2857) diagram. It weighs about 8 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.
