thanks mate. i was talking to an irish bloke who bought the cby 86 that had the 16inch wata's on it and from what he was saying my wheels "should" fit. i think he run 16x9-20 or similar and he is about to put a 30mm spacer on it as the rim still slightly sits inside the cby flares. but if you were to run the same size wheels with normal tyres for some grip racing then i'd say the rim would be perfect size.
