Expanding nut — a genuine BMW part, number 63 13 1 378 066. The number stamped on the part is 63131378066; BMW's catalog files it under the short number 1378066. You will find it on our Lighting shelf, under Turn indicators, front.

It fits every E36 body style (318i, 318ti, 320i, 323i and 325i, 1992–1999), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.

BMW draws it on 21 diagrams, among them Headlining / Handle (51_3800) and Wheelarch trim (51_4232). BMW's catalog calls for two of these at each place it is fitted.

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
