Perhaps one of the most endearing features of the early Minis with sliding windows are the external door hinges, that is until they are worn beyond repair and sag to the point that the door won't close. Replacements are available individually, but this is a set of 4 complete with studs and nuts(each one is different). For individuals see 14A6818, 14A6819, 14A6820,
14A6821 or hinge repair parts 37H3043,
37H3044 or
