Changed out the old ebony leather wheel which was looking very "used" around the spokes and replaced it with a wood / leather number bought on eBay. Not sure how to post photos so made it my temporary avatar. Not that hard but you need patience and a wheel puller with the GM "hooks" to dislodge it from the spindle. The burled cherry is a fairly close match to the oem plastic wood accents. Mounting instructions are readily available online. Guess I'll try to sell the old wheel on eBay.
