I am looking for the measurements of the 1948/53 1/2 ton grille and the 1948/53 1/12 ton grille. I do not know when the break off point is, I believe the grille from a 1 ton is the same as the 1/2 ton but not sure. I have a NOS grille but not sure what it fits, I believe it is for a large truck. :o ....g
