Flywheel Differences

[Duezzer]

Hi There,

Looking to find out the difference in these 2 flywheels.

986-114-012-05-M37 (for a 99 Boxster)

And

986-114-012-06-M37 (for a 2001 Boxster S)

Is it possible to install the 986-114-012-06-M37 into a 99 boxster?

Will it bolt up to the crank?
Will the 5 speed transmission still be mountable?

If anyone has drawings or pictures or a good discription of the difference I would appreciate if they could post them


Thanks
