aluminum flywheel troubles

[IH8DSM]

So i'm trying to install this aluminum flywheel on my car, trying being the keyword. I've got the rear counter weight on there correctly and the clutch fits but when i go to put the pressure plate on its got almost a half inch gap between the flywheel and the pressure plate. The flywheel is completely flat with no dowels in it, the clutch is recessed into the flywheels so its the pressure plate that is making it raised.

So heres my question do i need to use a aftermarket pressure plate, spacers and longer bolts or what? I've never installed a light weight flywheel on a rotary before and from everything I saw I thought it just bolted up and was good to go. I have no idea what kind of flywheel it is either.

Any help at this point would be appreciated
