ok, upon further research, I have determined that they stopped putting cab id plates on in 1949. That explains why I couldn't find them. Same thing with the frame numbers, what I thought were numbers with the flashlight last night turned out to be nothing in daylight.
The reason for the question is of course a titling issue.
The NC title from Spanky has "632261021" listed as the VIN.
The door plate has "f452-30 1021" plus the weights and stuff.
The distrubutor pad has "30217634"

It seems a might big coincidence that the title and the door plate share the last four numbers. Anyone have any idea where the first five might have come from. The 1947 owners manual with the nine digit cab number had me sure that that was it. Now I just don't know. Thanks,
Scott
