I have a big b&m hitek with a fan that it's squeezed inbeytwen drill and radiator. I had an o ring fall apart on my trans line while taking out my trans to swap flex plates and am thinking of replacing the big fitting with an fittings and new lines but skipping the stock heat exchanger up front and just running the cooler close to the trans this will clean up the front a bit getting rid of that mess in the grill ... The question is will this be enough without the stock cooler ? ... I would think yes but I've been wrong before.
