Any one know the size of the transmission line and the fitting going from the lower tranny line into the radiator? Any stores/websites? I am thinking the line is 5/16" and the fitting into the radiator being 1/4" but want to make sure. I'm in the process of replacing the last 5 inches of the line due to the flare nut being rusted onto the line causing it to twist when trying to loosen it out the radiator.
