James,
We've been through this many times before.
You can get the codes - they are in De Tomaso publications and on some of the Pantera websites - but apparently they are so old none of the companies can offer a current-day equivalent.
If you are going for a true OEM restoration, your best bet is to find a proper era paint chip sample and have paint made to match it.
If you are not that picky on originality, pick a color you like and go with it.
