Can you be more specific? If it's the dash pad you're after, the repro pads are fairly inexpensive and are of good quality for the '65s and '66s.
If it's a mangled radio cutout you're trying to fix, you can by a patch to repair it with. It should be welded in to do it right, but a real creative person my find otherwise.
If it's other parts of the dash, again the entire dash panel is made in reproduction, but definately needs to be welded in.
If you always do what you've always done,
You'll always get what you've always got
