help with some info on my duster

You are all over the the place with your questions so I will answer one.

The paint code is not in the vin. It is on the fender tag and build sheet. Your fender tag is under the hood by the battery, you cant miss it.

If, for some reason, it's not there, you will need the build sheet.

The build sheet (and not every car had one in it) can often be found in the seat springs, on top of the glove box, really behind anything in the interior.

If you don't have a build sheet or fender tag, you are SOL.
