OK - I can accept that there were different types of dizzys fitted, and I can also accept that Nissan Australia wouldn't have a clue.

What gets me the most is I buy all the spare parts for the A14 distributor from Bosch....and the dizzy cap doesn't fit, so which other one I wonder should I buy?

Here is the cap from the A14 dizzy, and the replacement one I bought - different size and completely different offside of the four plugs around the centre.

So I'm hoping someone will recognise it, or recognise the part number - so I can go buy some more spare parts. Also we can solve an interesting mystery too...that will be fun, wont it?
