Remember - I quoted from the manual for 115 chassis 300D, 1975 to 1976 - no turbo.
The alldata pages did not differenciate enough between variations to be useful. For instance, it did not differenciate between the three speed early 107 cars ('72 to '80) and the later four speed cars ('81 to '89).
So lets see - the only other semi-official post on the subject, OK Don's, agrees with me.
