 Hi Nigel,

I am looking into a W58 conversion as well. I have replaced the speedo gears (one in the transmission tail housing and one on the speedo cable assembly). Below are the Toyota W58 speedometer gear ratio sets and part numbers I found when looking at different gears:

Ratio Gears Plastic Gear#               Metal Gear#
2.7   30:11  33403-29105 30 teeth   33481-14020 11 teeth
2.8   31:11  33403-19245 31 teeth   33481-22020 11 teeth
2.9   32:11  33403-19255 32 teeth   33481-22020 11 teeth
3.0   33:11  33403-29115 33 teeth   33481-14071 11 teeth N/A
                                                    33481-35100 11 teeth N/A
                                                    33481-20090 11 teeth (possible replacement)
3.1   31:10  33403-29145 31 teeth   33481-22030 10 teeth (for 31 teeth plastic gears)
                                                    33481-35130 10 teeth (not sure if this is a match)
3.2   32:10  33403-29125 32 teeth   33481-22130 10 teeth (for 32-33 plastic gears)
                                                    33481-35130 10 teeth (not sure if this is a match)
3.3   33:10  33403-29135 33 teeth   33481-22130 10 teeth (for 32-33 plastic gears)
                                                    33481-35130 10 teeth (not sure if this is a match)
3.4   34:10  33403-39075 34 teeth   33481-14031 10 teeth
3.5   35:10  33403-19235 35 teeth   33481-14031 10 teeth

I hope this helps,

Jerry
