Vin trouble

Hello vets I'm new here. I recently purchased a supposed 76 roadrunner but it has a Dodge Aspen Hood, 7 1/4 rear end, and the vin comes back as 1968 Plymouth volare... At this point I think I'll have to register it as a custom vehicle with all the mix matched parts. Any help truly identifying this vehicle would be greatly appreciated, thanks in advance
Well, first off, you know there's no such thing as a 1968 Plymouth Volare. Volares were around from 1976 to 1980. So I'd suggest you start by finding a better vin decoder. The only difference between an Aspen hood and a Volare hood is the nameplates and trim on it. The hoods themselves are really the same. The model year of your car will be the sixth digit of the VIN. If it's a Volare the VIN will start with an "H" if it's an Aspen it will start with an "N".

Second digit in the VIN should be a letter denoting the trim level.

Third and fourth digits will be numbers indicating the body style. All two door coupes were 29

Fifth digit is the engine. Lots of choices here.

Sixth digit will be the last digit of the model year.

Seventh digit will be the assembly plant that built it. B is Hamtramck, G is St. Louis, F is Newark Delaware.

The last six digits will be numbers indicating the sequence number. Each plant starts at 100001 and goes up from there.

Let us know what you find.
