Hey guys im currently doing a clutch replacement and since it has over 200k miles on it i just bought a new flywheel from Napa and i didnt notice that it was missing the center piece where there has 6-8 holes for the flywheel bolts...i'll upload pics down below.

 

this flywheel has the center peice

 

 

 

this flywheel does NOT have the center piece from napa....

 

 

 

 

Now my question is do i return it for a flywheel that has the center piece or am i suppose to buy the center piece and press it in? a quick response would be greatly appreciated. Thanks again US community!

The center piece can be transferred from the old flywheel to the new - it's held in by bolts.

What car is this on?

The later flywheels do have a "floating" section in the middle to aid in vibration and shock dampening. It should be transferable from flywheel to flywheel, but you need to make sure you have the proper torque spec for the bolts.

My car is a 2000 subaru outback 2.5l motor, but the date of manufacture is June 1999 <<useless information? anyways Ive never seen this before so i might just opt for a different flywheel and wait an extra week....but then again im still out of a car to drive...whats the chances of a shop pressing in the center piece cock-sided? Again thanks for all the replys

I believe what you have is a dual mass flywheel.  The center piece should just swap.
