I've already done some searching, I saw that thread but it didn't help much.
I think it will be hard to match the 40th anniversary interior and exterior. I looked at a lot of NRG handles, Nardi, MOMO, Sparco, and a few others but I feel like I'm missing a lot. I think I'm mainly going with carbon fiber, black leather, red stitching, or dark metals. I think the flat black handles might scratch easily since the handbrake is used so much. Polished will look weird with everything in my interior.
I was looking at this Nardi Torino CF handle. I think it may match well.
