Aluminum Flywheel problem [56k probably not]

So I went to put my engine back in the car about an hour ago and noticed that my flywheel seemed larged than the stock one, so I pulled it off an checked.


This is what I found. I have no idea why the aluminum one is bigger, and it present me a problem because it doesnt fit the transmission. The thing is my stock clutch bolts right up to the flywheel and the clutch disc fits perfectly on the friction surface. And the picture for the na flywheel from mazdatrix matches mine perfectly from what I can tell.
So I ask you, what the hell do I have? And whats my best plan of action.

You need the Mazda counter-weight that is a standard part on auto-tranny cars, like the ones seen on this page:
http://mazdatrix.com/flywheel.htm

Most light flywheels require the stock auto-tranny counterweight, or come with the counter-weight already as part of the package.

You MUST get one that is appropriate for the weight or your rotors and front counter-weight, since they act together to make up the balance on the rotating assembly. It isn't hard to get the right one; I just mention this so that you don't think ANY counter-weight will work on any car. It won't.

I HAVE a couter-weight, the flywheel is physically too large to fit in the bellhousing, but bolts up to a na pressure plate.

And if you had bothered to read my post at all you would have noticed that I said that it didnt fit in the TRANSMISSION, not the eccentric shaft

I thought it was a turbo flywheel at first too, but if it was the NA pressure plate shouldn't have been able to bolt up.

it's an n/a flywheel but why it's too large i don't know. is there any part numbers stamped on it? if it is a mazdatrix flywheel give them a call, since they made it they should know the size measurements what it is made for.

might be a miata flywheel, just a guess though.

Look at the bolt holes and the dowel pins on your aluminum flywheel.
They are all in the wrong place.
If you had bothered to notice this, it's obvious it doesn't fit.
Shoot the idiot that sold you this thing - it obvious doesn't fit for your application.
