I think either way you go the gauges will be somewhat obstructed because of the smaller diameter. If you so go with Grant, they make an awesome billet adapter that matches the wheel, plus there are many billet horn buttons available as well. I have seen just plain smooth horn buttons, ones that have a bowtie and I think there was one with flames.
