81 vin question
« on: May 07, 2018, 09:32:29 AM »
I removed the engine side firewall heater/ac box .  I found part of the vin stamping.    Using fake numbers,,I found
On the firewall:    2BN123456
On my dash vin, the last numbers are 7BN123456

Why would the first digit be different?

Those numbers look the same to me. What you are seeing as a 2 on the firewall is most likely a 7.  On my tata some idiot at the dmv made a Z into a 7 and 5 into an S.

I would agree that a 7 can look like a 2 but both those numbers are in the lineup and they dont resemble each other.  One starts with a 2 ,,the other a 7.  I hope this isnt an issue.

I don't think it needs to be a 7 at all.  I may be off base here about the firewall, but on the engines, The first digit was traditionally a 2 on every Pontiac because Pontiac VINs started with 2.  It would never have been 7 for any reason, and it clearly wasn't intended to be a consecutive chunk of the VIN, although that would have been nice.  I think any shortened version of the VIN could start with 2 and it wouldn't be strange at all.

When they went to the longer format VIN's, the 2 meaning pontiac became the third digit of the VIN's, but I just think old habits die hard.

In addition, the 7 in your VIN is a check digit and would be useless for car identification.

I know....I was more curious as to why,,,but I read where the guy in California needed to remove his ac box after he had the car restored to prove to motor vehicles that they matched. (I think I read it here?)

Ok that sort of makes more sense.  Thanks
