Looking at the way he's laid out his other pics it appears both Vin and Trim tag are on the brown car? .
Here's clickable links to the other pics. .

There's no Vin or Trim tag shown for the parts car that I can see yet I think the Y code paint is for Yellow so could be off or still on the parts car and he's mixed up the pics? .
The tags don't look like they've been moved and I see the 138 Vin is attached w/ the flower rivets...is this correct for '67? .
Is there a 12 bolt in one of the cars? .
Here's a link to some decode info and more stuff you can perhaps verify a few things yourself...check interior colors etc. .
