What gasket for Rear Manifold/Downpipe block-off/wastegate mount

Hey Guys,
Do you know what gasket to use for mounting the wastegate on the CT kit on the rear manifold? I imagine one for a block off plate would be fine too. The only one at the parts store has ridges on both sides that go into the manifold and downpipe, but the plate doesn't have that so it's just trying to crush it instead which I would imagine makes a poor seal.
Thanks!

Is that what you're using? That's what the part store had, but it's not flat, it's rolled around the inside edges.

When I bought the ct kit used it had that gasket, I bought the one I linked last year to replace the old beat up one.
As far as I am aware its just the stock gasket inbetween the wastegate perch and rear mani, nobody sells anything special or different.
You can see the gasket when I first got the kit, has the metal ring on the inside

Ok, here I was assuming we needed a flat gasket to get a good seal, but if that's whats working for you then that's what I'll use.

Yes, I ended up getting a walker gasket as that was all the parts store had, but it was basically the same thing.
