And SKOKIE- Be sure and check your valve cover gaskets too; as they can leak in the back and run down the back of the engine. Just my .02 worth

Most FelPro OilPan kits - the original cork style will come with both "Thick & Thin" front Pan seals to cover you.
If you buy the FelPro KS2600 (complete engine kit) it will have both style front pan seals as well.

But when working with the "1-piece retrofit design" - you need to know which front seal you have
