Hi all. having trouble figuring out the sequence of installation of the gaskets between the intake manifold and the carburetors on my wifes BJ8. I have a metal faced gasket, a black fiber gasket, and a red fiber gasket. these are the gaskets that go between the manifold and the plastic block, the plastic block and the heatshield, and the heatshield and the carburetor. Have checked the shop manual( hayes and the big green one) no luck. please help
