Used only the first 1 1/2 years into this body style, these GMC grilles stand out for their different shape and very heavy duty construction. Because of it's weight of this assembly, it sets on the frame rails and is given extra support by a pair of 1 1/2 to 2 ton steel rods extended at an angle to the frame rail. In order to make room for these braces factory holes were placed in the front of the inner fenders. Rubber seals are held in place by metal flat rings. These photos tell the story.
The grille has three horizontal bars and uses a heavier gauge metal than the four bar grille introduced in 1949. This same unit is found during 1947 and 1948 in all 1/2 ton through 2 ton GMC trucks.
On these early 1/2, 3/4, and 1 ton trucks the splash apron from the grill to the bumper is even different. The front bumper is the most unusual. It is rounded much like an automobile and has three bumper bolts on each side. They all have the small grill guard on the 1/2 and 3/4 ton.
Some suppliers of 1947 - Early 1955 bumpers and grilles state they are all the same. Wrong! The 1947-1948 stands alone!

Note the 3 bumper bolts. The center secures the front splash apron and securing braces. The other two are used by the dealers to attach GMC accessory larger grille guards to the bumper.
