Gen V Aluminum Flywheel on Gen IV

[blknblubkrdude]

Is the V flywheel dimensionally the same as the IV?

I've been researching and haven't found any confirmation of this.
I came across two replies mentioning the IV Steel being used on a V, but with no example to back it up.
If you or someone you know has one lying around I'd be willing to buy it for testing.

Give Scott R. at Prefix a call. He will know conclusively.

I have one on my ACR. Flywheel and clutch setup from a gen 5.

I took Steve911's advice and here is the answer:

"It shares physical dimensions except for the steel clutch contact surface.
The gen 4 and Gen 5 have different diameters of steel contact surface. If you have a gen 5 flywheel you need to use a Gen 5 clutch"
