okay I'm new at this so be nice, i'm the proud owner a 74 k5 with a built 350,203,44,12bolt. On a resent stop the oil from dripping (i know should not even have tried) tune up I managed to pretzel one of the connector on my engine oil cooler. this cooler is an original factory option on my blazer and is no longer made according to chvey. Could you guys tell me wear i can find some sort of replacement OEM or aftermarket. I think the connector size is 3/8 or 1/2 NPT, any suggestion would be great.
