if you're talking about the orange car in your avatar pic...i think a nice black/white herringbone would set it off nicely. I am actually doing the same thing with my 72 Demon. The bench seats came in a larger plaid pattern, but doing the bucket seat inserts in mine, so I chose houndstooth over the plaid. I have pics I can attach that are from a Duster with exactly what I'm doing. I also attached a low bucket seat that was done. My car is white with black stripes and black guts...so the orange will make it pop!
