Got a box 4x4 esc cossy supposedly a ''QUAIFE'' . I can't fit a std clutch cable as it won't fit through the hole in the housing. I have been told this is because the Quaife housings were slightly too small and you must drill them out. Anyone heard of this? The under neath of the rear half has a ford oval cast in it. Could it be quaife internals and bell housing with ford rear casing? or am I just being optimistic?
