Drilled into the 4AFE Corolla harmonic balancer pulley are two M8 threaded holes. I want to make a tool to hold the pulley and need to know the spacing of the two holes. I tried measuring them when still in the car and it appears the spacing is either 58mm or 57mm. I've found that often the Japanese still use soft conversion of Imperial dimensions and 2.25" is 57mm so possibly that is it. If anyone has a pulley or engine out of a car can you please measure the hole spacing and let me know? Thanks. Peter
