Yeah, My dash is the same.
Im going to guess, for the best color & texture match... look in the "parts" section of ebay motors. Find a part of your car that has the padded vinyl, and buy that. Remove the padded vinyl from that part, and put it on your project.
For example, the entire upper and lower dash of the Mitsubishi 3000GT, and the doors is padded vinal. If I wanted to do what you were doing, I would get a door panel, strip the vinal off that, and put it on the "hood" I was making.
