Its probably upper and lower water necks. The upper one has the thermostat in it. The upper one has the odd shaped gasket and the lower one is just a round one with 2 holes in it. I bought a motorcraft thermostat from rockauto and it came with the gasket. The one I put on from Oreillys this summer had already fallen apart by the time I took it out. It was almost 20.00 also.
