So I noticed a difference in radiator side armor. Some halftracks have a larger support bracket that bolts to the top of the frame rail and then to these pieces. If it takes the large bracket there is an extra hole, the one the tip of the pen is pointing to. Also this hole and the mounting hole below are not countersunk like the one on the top. Oddly both of these are off M16's I'm fairly certain. The one on the bottom definitely is. Anyone have an extra set you don't need?
