Catalytic Converter Gaskets?...
Some here may have seen my other thread where I mention that I removed my CAT to check the condition. It's the 1984 Corvette type with 4 bolts on each flange.
There were no gaskets on these flanges, but I know that gaskets are available, so I am wondering if a P.O. removed them, or if it never had them to begin with.

There were gaskets originally. At least there were on my car. Started getting hard to find around the turn of the century.
I always used to just get sheets of gasket material and cut em out.

Re: Catalytic Converter Gaskets?...
Yeah, I already have one new gasket. I ordered it by mistake a few years ago (thought it was for something else) from NAPA and never returned it.
So if it's supposed to have gaskets, I'll need to get only one more...

All the factory ones I've seen didn't have a gasket.
