Has anyone got a reliable source for the decoding of the VIN and trim tag?

I've found various sources that give me some information, but I'm lacking some other.

VIN so far shows it's a 1979 Bonneville 2 door coupe built in fairfax (X-code), but the engine has a R code which is apparently a 350ci V8 4-bbl with 160bhp, but I'm not sure if this will be the Chevy, Buick or Pontiac engine or if this even matters when buying parts.

The trim tag shows that it's a 1979 Pontiac Bonneville 2 door coupe built in Fairfax with carmine red interior but has a D code and I can't find what material that means. I also can't find a list of the numbers that relate to the options section. It also shows it was built in the second week of January and was carmine red on the lower but has a code of 79L for the top, which I can't find the information for.

Unfortunately you're a year too early for compnine.com. Have you tried talking to one of your local dealers? You can also purchase an information package about the vehicle from the GM Heritage Center https://history.gmheritagecenter.com/wi ... ailability or in Canada from Vintage Vehicle Services http://www.vintagevehicleservices.com/.

I'm in the Uk so no local dealers annoyingly, but the heritage centre is great information thanks

Sorry, I remember now that you are in the UK. Do you know which country the vehicle was originally marketed for (Canada versus US)? This will determine which of the two groups you should order a package from. You can see on their site the information that will be included. It may or may not be helpful enough for what you want.

It was built in Fairfax, Kansas apparently. I believe I've managed to track down the correct information for the ViN from an old Pontiac book I found online but the trim still confuses me.

I have no idea where the car came to the Uk from either as it was over here when I bought it
