Expert Reply:

The difference between the Derale Stacked-Plate Engine Oil Cooler Kit part # D15602 and part # D15605 is that the former comes with a 2-3/4" o-ring and the latter comes with both a 2-3/4" o-ring and a 3-1/2" o-ring. These o-rings are used to attach the sandwich adapter to the engine block (see photo). The 3-1/2" o-ring is only needed for 1963-2007 GM small block & big block V8 engines.
