does anyone know the stock sizes of the barbed fittings that come out of the radiator for the tranny lines?? i have only 2 -6an fittings and lines, the cooler and 1/2" NPT to -6an nipple attachments for the cooler. now should i just use the stock clamp on the barbed fitting on the rad or should i switch them out for some pushlock barbed fittings maybe?
