Hard to tell from the photo, but the inserts look like the grain used on '69 Belvedere & base Road runner benches, or VW Beetles of many years.
I'm pretty sure Legendary will make custom sets & colors, but for accuracy you'll have to do some research or send a sample.
I'm surprised the car would have a white dash pad - they reflect into the windshield.
Was it actually raced like that, or is it a subsequent re-do ?
