Can I get a carfax or background check on these please???

[Camfreek]

I got these two two cars and the one I know most of the history but I have been pulled over twice and they alwats check the vin and never ever have they checked my vin??? Here is that one_1G4AK4790EH465571 The other is supposed to be a real deal 84 GN, but the title just states regal?? It was a drag car and the trunk is now fiberglass and all the factory stickers have been painted over. I belive it is cause some one would have had one hell of a time changing everything over on this car!! The number for this one is-1G4AK479EH556935. Any help?? Thanks
