Yeah im positive. I clearly remember having to strip down my sunny sedan to get the flywheel off as the A15 flywheel i supplied the shop was stuffed, the ring gear was ripped to shreads so they needed another donor.
I mite go have another crack in the shed as how can changing cars it suddenly not work
The only other thing is that is there a difference in the 56a boxes throughout the years? Do they differ at all in the fork/release bearing as they got more modern etc.?
