4.0 OHV oil pan gasket set: what are the washers and orings for?

[freak]

I bought a felpro oil pan gasket set for my 1997 4.0 OHV. In the box are 2 orings and 2 washers with an oring molded into it. Where do the washers and orings go?

They sell the same oil pan gasket for the ohv and sohc engine
Those washers and o rings and for the sohc application
