Oil Cooler Seal, Doghouse Cooler to Early (Single Relief) Case

This is a special adapter seal.  It allows the '71 and later "doghouse" type oil coolers to be installed in the '70 and earlier single-relief engine cases.  There is a tapered side that faces down when installed.  Only two are needed from the adapter to the case.  Use the red seals between the cooler adapter and the cooler itself.
