I am trying to identify a grille that someone does not know what it came off of and it is not local. I have the KB1 1947 on my truck but it is bad and I found one that is good but it looks the same but I can't tell if it is larger or has something different from mine.
if what was side by side? a K1 and a K5 or any between? the answer is nothing is different, a 1-5 grill assembly is same, has a hood the opens from the front, so grill assembly is flattish on top with a latch assembly, and a wire terminal bar for headlamps, also the sheet metal flare out on sides with bolt holes for fenders. the parking light assemblies are square.
a K6-7 has no side flares for bolting fenders on, there is no hood latch assembly on top, the parking lights are rectangle.
so, I guess the VERY easiest to tell between a 1-5 and 6-7, is parking lights, small 1-5 trucks square, big 6-7 trucks rectangle,
if this doesn't answer your question, I guess I'm not getting what you are asking,
and best bet is go to photos and look at them,
