Default Undocumented Vin #

My VIN # is 1G1YY3182K5119894

Note digit #7 It is 1, no listing.

Also, note my year is 1989 and the last five digits are 19894. Co-incidence?

If you are looking in compnine, they don't have everything. Just go to a chevy dealership and ask for a VIS report with the VIN.

And yes, your 7th digit is supposed to be a 1. You only have Passive Restraints.

The VIN is correct for an '89 'vert/roadster - the 'check digit' 2 (ninth digit) which validates all of the others is correct so I doubt your claimed undocumented.

Here's a GM VIN Card for 1989 that you can actually decipher all but the 'ninth' digit of a GM VIN. The ninth is a 'check digit' that uses a numerical algorithm of the others to validate it.

Haynes is wrong.

The factory manual lists 3, for convertible, which I thought would be listed as 03 (as is 07 or 02 for non-convertible).

Instead, there is 31, just before the engine code. That's where my confusion came from.

Body types in the factory manual are listed as [07 Coupe, 2-door hatchback], [02 Coupe 2-door hatchback], [67 Coupe 2-door Convertible], and [3 Coupe, 2-door Convertible]. I didn't know where the 1 came from, and am still not sure.

Not a big deal. I was just curious.

The '89 VIN Card I posted explains it very clearly if you check the explanation for 6th digit. You'll see explanations of 07, 67 and all of the other GM body types.

Ahhh. I see. There is confusion in the factory manual notes about body types, making it look like body types were two-digit, when it's actually a 1-digit code.
