Well, regarding serial numbers on frames…
I don’t know about 47-55 trucks (despite owning a few), but I did find the frame serial number on the 1970 C10 I have that I got from my Uncle&Dad&Grandpa. It was on the LH frame rail on the top side underneath the cab and was very hard to see. If the cab was on and the frame painted, you would never find it. Knowing the history of my truck, I knew it had no issues. But it was still satisfying to see the frame serial number match up with that on the cab.
