I'm confused. What is it that couldn't 'line up properly'? There's nothing on the RF fender/hood except white. The only thing that crosses the two planes is the headlight. That sounds more like a template creation problem than a 'paint alignment' problem. If we don't know what doesn't align how can we fix it?
OK. I loaded the .car file and it looks like the 'paint' was done on the wrong model. In other words, while it looks like a 'Chevy' it seems to be on the wrong body type, as though someone put all of the Chevy parts on a Dodge/Ford/Pontiac. Whatever happened it's definitely screwed up. I can't really say if it's salvageable or not, but since it's such a simple scheme, it might be easier to just redo the whole thing. The added benefit of that is that the templates are so much nicer these days. Something to think about.
