Anyone who has installed a universal bullet mirror on a Mini door knows it will not provide proper viewing. This mirror is designed specifically for the Mini and will give the correct viewing angle for safety. The special curved base is the trick. They fit only the specified side.
Choose right-hand (GAM107) or left-hand (GAM108) for flat glass. See GAM107C/108C for convex glass.
The door must be drilled to install on pre-1980 doors, and hardware is included to complete that installation. For 1980-on doors with two (2) nut inserts, use M90999 installation kit for right-hand side and M90997 for left-hand side (each kit sold separately).
