Broncokak, youre tag looks like the vin tag off the older mustangs the ones i had were like that facing out so you could read the number from outside the vehicle some were on passenger side and somme were on the driverside. i have seen body buck tags on all the mustangs i worked on in several locations radiator support,badery tray side wheeelwell firewall under fenders etc. never know where they may pop up BUT most broke down into where they were built,Metuchen cars were on the firewall, san jose were on the radiater etc.
