The centercap of the wheel is covering the hub. I just checked Mar-K, '47-early '51 used 9 boards, late '51-'53 have 8. The gas tank under the bed says '47 or '48. Can you post the Serial Number from the cab? I can cross reference it to the ID material I have. To my knowledge, the ADs were not stamped on the frame like the later trucks were, but if it is, look on the top of the left frame rail near the steering box. That seems to be the common location on the later trucks for the serial number to be stamped. Also, if you can, get the number from the engine. It will be on the machined pad just behind the distributor. I have to codes for the engines as well, just so we can find out what it came out of.
