I have a 1990 3/4 ton Sub /forums/images/graemlins/burb.gif with a 350 and no oil cooler. I picked up an oil cooler setup from a 1978 3/4 ton pickup /forums/images/graemlins/truck.gif with a 454. Does anyone know if the adapter that goes between the block and the oil cooler is the same for these two trucks? If not where's the best place to get it? Napa, Dealer?
