3.1 set is made up of a DAM2806, 61 tooth Crown Wheel with a DAM2808, 19 tooth Pinion

3.2 set is made up of a DAM6327, 59 tooth Crown Wheel and uses the same Pinion as above.

These were only made by the factory in A+ types gears, but will fit the earlier boxes OK, though, you may need to grind some material from the Mainshaft Bearing C Retainer to fit the Pinion in.
