Have you had any luck in your search for the cross reference between the W30 and the Leyland diesel? I too am just starting a rebuild of a W30 (actually it''s a Four-91 which is suppose to be the same). I would appreciate any info you have found concerning the cross-reference of parts.
Are you sure the W30 and is based on a Ford Leyland? I have read that it is based on a British Leyland. Do you know if the Ford and the British Leylands are different or the same?
