Blown Wastegate Diaphram

Fellow Turbo Wrenchers,
I opened my stock 964 turbo wastegate and found what is depicted in the picture below. Possibly an improper installation?

I think the diaphram is trashed because when I pull it back into shape, I can see light through the creasing.

No wonder my boost never seemed to taper off...

I cannot find a P/N for the diaphram. Anyone know what it is? Better yet, does anyone have one that I can buy? If you have an aftermarket WG (TiAL) maybe you could donate your old diaphram to a good cause...

Thanks,
Mark
