OK, big dilemma here. I got the replacement nipples from Ray Catena using part#915013-013002 and got them installed into my oil cooler. The hoses I got from my local auto parts store have the part # 6031800430 which equate to W0133-1715552 which is the correct part listed at Fastlane. The nuts on the end of the hoses I got are A LOT bigger than the nipples on the cooler. Just for the record, I did put the smaller diameter fitting into the radiator. Am I missing something here?
