Okies, we have a bigport AE82 motor in our hachi, the dizzy is the original unit with the plugs facing upward (ie out the side of the dizzy), it's a Nippon Denso unit i think however when we go to the shop to buy a new dizzy cap (it's broken) we are presented with a bosch unit that doesn't fit. Is the bosch unit the right part for another 4AGE or have we been given the wrong bit?
