Spottlights,
The main difference between the rear hood bows relate to where it mounts.
Up the late 70's the rear bow has a 'dog leg' below the hinge to allow it to mount to inner side of the rear guard. In later models the mount point was moved to the outer edge and the 'dog leg' was removed.
The spare wheel on the later Mokes is a large metal bracket with four bolt holes to attach it to the body. Earlier Mokes have a simple 'S Bolt' with a thread at each end and secured into the rear panel through a circular reinforced section that looks a little like a donut from the inside.
Grills are all the same.
As Tainted signs off with, If in doubt ask :-)
