factory grease pencil marks?

My 67 still has them. Didn't see any around the fenders when I had them off, but I wasn't looking either. I would like to try and figure out a way to preserve this, even though the original 327 is long gone.

I confirmed yesterday that I still have the original engine and transmission (matched the serial numbers to the protect-o-plate). I don't have a particularly collectible truck (long bed with no cool options) but its still neat.
