M38 Markings

[Blizzard]

Right now I'm in the process of sanding down to find all the original markings an was wondering where all to look and what i might be looking for?

I know about where to look on the hood for the hood numbers, but sadly I think they are gone or will be difficult to find due to the fact that they may have been sanded away many years ago.

On the left rear bumper I have seen some markings but they don't seem to match any I have seen in pictures.

Any help would be much appreciated.
