Model Car World, known is "MCW" does a line of absolutely correct factory paints for scale cars. The metal flakes in them are ground precisely to scale size, so you get a perfectly true 1:1 representation of the paint. There really is no finer paint on the market. Look at my '56 Chevy here done with MCW paints;
MCW also has a catalogue that you can order which gives all the correct paint numbers and colors for each manufacturer by year. You can then order from Dodge's inventory. The colors come airbrush-ready, pre-thinned, and go on beautifully.
Here is their website. This is the page with Chrysler's colors I suspect that the color you want is "6761 Gold Metallic"
