yes, the smaller is 1"x3.25" [happen to have one laying on the desk

] it's unpainted stainless and held to the pillar with 2 small spot welds, you might see evidence of them if the tag is gone - it only has the vin#, the other is the data plate with GVW and such .... without the vin tag there's no way to positively ID the truck - but if it's on a different chassis anyway, call it whatever grill you put in it
