Question SA 12a - Exhaust manifold to downpipe gasket?
Trying to figure out what to use for a gasket between the exhaust manifold and the 'downpipe' section. Seems like the gasket is NLA...
This is for a 1980 so SA 12a...
Anyone have a solution?

Thanks!

I checked and what I have are pre 1979 12A gaskets. I tried fitting them to my 1979 thermal reactor and they are too small.

Bummer
If anyone else has any ideas on gaskets, please post.
Is there a DIY material somewhere that stands up to rotary EGTs?

It would have to be a layered metal gasket for sure. Have you tried to call Atkins or Mazdatrix to see if they had any laying around?

I just wonder if they have any laying around. Maybe they don't offer them for sale but have a couple of them. I figure its worth a call just in case.

Looks like Advance Auto still carries it. It allows me to add it to the cart whereas other places let you but say its out of stock when you go to the cart. Might be worth a shot!

I ordered 6 and have tracking numbers. They split it in two orders. One of the tracking numbers worked and the other did not. One of the tracking numbers says Friday. I'll report back how it comes out.
