Does anyone know a source for 2" 3-bolt exhaust manifold block-off plates for the neck base of OEM size c1 manifolds? I've looked on JEGS, Summit, EBay, google etc and can't find anything smaller than 2.5". My engine has been sitting a while and will be sitting for a long while more and I want to seal it all off. Thanks in advance for any help.

I'd just make one out of any sheet metal I have laying around...or redrill a 2.5" plate...

Use a couple of plastic lids (coffee cans for example) with three holes drilled.

You could also remove the manifolds and use these.

Thanks all for the advice (especially the coffee lid idea)!
