Anybody out there know the part number for the 'bolt' that holds the hinge together? My 318i seems to be missing one of them and the upper slot is less narrow that the lower so a simple drop in bolt plan does not work. So I am guessing the upper part is a bolt and the lower part is a threaded barrel with a cap for the bottom?
If not, does anybody have a hinge they could part with?
Thanks in advance.
