I have to change a gearbox in a 306 hdi as it decided to implode and i have a few be3 boxes out of 405 diesel's. The boxes will fit but it says that the hypoid gearset is 19 x 70 in the hdi box and the other ones seem to be 19 x 77 or so. What does this mean? Will it affect the engine rev to box speed. eg 2200 rpm in 5th is 100kph. Thanks Richard.
