lower and upper differentiate the 2 colors, but the 2 tone patterns vary, most TF 2 tones were split at the feature line, but there was also different treatments above the window line including everything one color except the top of the roof, look thru the gallery at 55-59's to see various patterns,
my 58 has one pattern [from a factory foto] , but sometimes the roof above the drip rail might be the light color as well, I've never seen any real documentation other than advertising pictures
