Centering pin — a genuine BMW part, number 54 31 8 163 671. The number stamped on the part is 54318163671; BMW's catalog files it under the short number 8163671. You will find it on our Exterior Body shelf, under Other Sliding Roof / Folding Top parts.
It fits the E36 convertible (318i, 323i, 325i, 328i and M3, 1994–1999), with the M42, M43, M44, M50, M52 or S50 and other engines — and the European-market versions.
BMW draws it on the Manual/Electromech.Semiautom.Folding Top (54_0180) diagram. BMW's catalog calls for two of these at each place it is fitted. It weighs about 11 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.
