Turbo Riviera Gasket NLA?

[turbojimmy]

I know GM stopped making the turbo Riv gasket a while ago. I'm trying to get one from NAPA (p/n G26951) and they say it's "backordered from the manufacturer" which means to me they can't get them anymore. I haven't had any luck with the copper ones that are available from various vendors.

I know a gasket wasn't there from the factory but I can't get mine to seal up. What do I need to do in order to go gasketless again? Take the header and turbo to a machine shop?

Thanks,
Jim

Okay. I found a source for the gasket. It's modeled after the Riviera gasket but is bigger to prevent interference with the exhaust flow. Since I have no patience and can't wait for the gaskets to get here (ordered 2) I took the turbo off and flat-filed the header and the exhaust housing on the turbo. Put it back together and it's fine - LEAK FREE!

Now I'll have an extra $32 worth of gaskets.

I found the link on one of the 'other' Turbo Buick boards:

Click on "Parts". I think you can search on "gasket" too. The site isn't working for me right now so I can't check.
