Can anybody help? I am fitting a yb engine (2wd yb red-top) into a westfield and am trying to bolt it to a 2wd mt 75 gearbox (as this is a really good installation and fits very well). The bell-housing will bolt to the block and the spigot/input shaft locates perfectly into the crank. However I have 2wd cosworth flywheel and clutch that generally looks like it should fit however when I offer up the engine to the box there is something adrift with the clutch operation as there does not seem to be any adjustment. Do i need to fit a 4wd flywheel or more likely do i need a mt75 4wd clutch operation arm and slider sleeve? Any ideas very welcome? ......please......
