I know this is an old thread, but along these lines, I'm looking to replace my oil pan gasket (it leaks a lot.)

When I look up parts for my year, which is an '81, it lists the 4 part cork gasket as the only replacement, but if I look up, say, a '92, it lists the one piece rubber one that everyone recommends.

I know oil pans changed slightly around '83 or '84 since the dipsticks are different. But are the gaskets the same? Would the one piece from a newer 4.9 work in my '81 300? Thanks.
