In one of Scott’s (Qcode351) Saturday morning garage videos, he found a VIN stamped on the inside upper portion of his firewall. His was a 72 - I’m not certain if this location would apply across all years but it would not surprise me if there are additional hidden stamping in addition to the apron ones.

Link to the post and video - hope this works


That's not a partial VIN, it's a panel identification stamping. I screenshotted the video and it's pretty clear that it says "D1ZB65", which means it's a 71-up Mustang panel, for hardtop and in this case, sportsroof. The convertible firewall is different and would be stamped D1ZB76.

You'll find these stampings all over every car. Here's some stamps from a 71 sportsroof I own.

I have a 71 Mach 1, a 73 Mach 1 and 73 Convertible all loaded
There is supposed to be a vin underneath somewhere. A 71 Boss I had 40 years ago had to be verified by the highway patrol because it was from out of state. Would need to have your original panels underneath which sounds like you do. Also a 68 Shelby of mine had one underneath. I believe somewhere near the transmission and firewall, but really don't know for sure. I was always led to believe this was privileged info. I am concerned this is an actual stolen Boss vehicle. A Yellow competition suspension car should have a better serial number than the one on the dash so why erase that. Never understood the logic attaching the number to a dash part. I hope you get good news whatever the outcome. Good Luck

1971 Mustang Mach 1 M code 351 4 speed
I had a 1971 Cuda that I bought from a classic car dealer in Michigan back in 1995. The idiot dealer wrote the vin number incorrectly when issuing the title and the state issued me a title with one additional number in it. Moved to Florida in 1998, and when I went to register it, because I had put the car up for sale, Florida immediately told me it was an incorrect vin number. I contacted the dealer in MI and they told me to send them the title and they would fix it. Well a guy showed up to buy the car and he wanted it now, said he would deal with the title. Sold the guy the car, and he went to the DMV, and they sent him to the police to check the vin's on the car. Well, they found out that the car had 3 different vin numbers, none stolen thankfully, but none the less it had 3 vin numbers. The police said that the car was a 1970 and not a 1971. They ended up issuing the guy a state vin number.

Back in the 1990's when people were restoring these cars, there were no replacement body panels, like we have today. So, if you needed sheet metal, you just went to a junkyard and cut off what you needed and welded it onto your car. Apparently, when this car was restored, they cut pieces off the front of one Cuda, and the rear of another and welded them to this car. So, one of the hidden vin numbers in the front was from one car, the one from the rear was from another car and the dash was from a third car... So, it does not have to be a stolen car, pieces could have come from multiple cars.

Only hidden vin numbers in Mustangs that I am aware of are the ones under the fenders, and those can easily have been removed or altered. How many cars have you seen that the fender aprons have been replaced on? A lot, and I can assure you those vin numbers were never put back on.

These old cars were so easy to steal and change vin number on that it is a joke. You will still see people selling titles with the dash vin on eBay all the time for rare cars.

In over thirty years of owning, restoring and parting out dozens of 71-73 cars, I have *never* seen a stamped VIN on the chassis anywhere but on the tops of the outer shock tower flanges. I've heard lots of stories and second/third/fourth hand info, but never seen a photo or an actual example of this mysterious "hidden VIN" on any 65-73 Mustang.

As far as the OP's car, it wouldn't surprise me if the dash was swapped either accidentally, or in what we used to call a "screwdriver registration". Some guys I knew decided it was much easier to swap the dash panel VIN over to their next car and change the color on the registration, than deal with the DMV.

1973 Mustang Convertible, 302 Restored to Factory Stock.
I ordered a Marti report for my 2f05h . The only vin number on the car is the dash. The previous owner bought it as a Boss 351 clone 22 years ago in Kentucky. The marti report says it's green , fmx auto, ginger interior no fold down back seat , regular shocks. Mine is grabber yellow ( I had the whole interior out and it's definitely original ) 4 speed, fold down back seat, staggered rear shocks deluxe black interior......... Whomever did the "cloning" did a perfect job. Thoughts?????
Nice car. Seems to me someone along the line restored/cloned it to their liking.
