Hidden Vin #'s

those areas mentioned are going to be it. i once bought a 70 coronet 2 door. upon removing the carpet, i found the front half was a B5 blue coronet 440 and the back half was once a burnt orange coronet 500 that had been welded together right at the floor seam. thats when i learned all about B Body , sequence number body stampings. it was quite a suprise lol. anyways , if it were me, i would go about my business and forget about it. in the end , it isnt going to effect anything value wise, unless this car was an original 440 6 pack car lol
