8The early steering racks had a 7 teeth pinion and 23 teeth rack. Here I am restoring the 066 rack and a later 4.2 for comparison.
The 3.8 did have a flat cover over the rack retainer.
Different fixing of pinion to rack housing.
Top, the earlier smaller pinion with 7 teeth, below the later one with 8 teeth
Close up, below the later 8 teeth
Both racks disassembled and ready for further inspection.
