Bathroom faucet - flange doesn't fit

[B.A.]

I'm replacing a bathroom faucet. I think the original was a Delta from 2004. I'm replacing it with a Moen.

The sink is compact as it's in a 1/2 bath. The sink flange seems to have a gasket built into the cultured marble.

As a result, the Moen supplied flange doesn't fit through the opening. Neither does an old Delta flange that I had laying around.

Pictures are attached. You can see the built-in gasket in the photo. The old flange is also pictured.

Do I need a smaller flange? Or cut the built in gasket?

Thank you.

Anyone have any advice on this?

Thank you!

Never seen this. Is it possible with a sharp utility knife to cut away the little resin over the ring and then from the bottom tap it up from the bottom? Some of these type sinks do not have an overflow drain. Most faucets sets are packaged with an overflow drain.
