I can't see the pan gasket being fun to do in car. I have been buying the Felpro conversion set. A bunch of gaskets for slightly more but just a regular cork pan gasket. I also used either the 292 Ford, the one Felpro sells as an Olds replacement or the AMC 6 or supposedly the AMC 360 seal. These are easy to install. What isn't easy to do is remove the rope seal. Too bad Olds didn't use these factory or changing the rear main would be doable with the pan off.
The Mahle gasket I have is a set of 4 I believe.
