For those that are interested, I found the rear hub covers. WRV had them but at "dealers price". Bill at Saddleback parts did a lot of research for me and found a vendor (PhoenixUSA,Inc) for $127 with 2nd day delivery. That was still cheaper than WRV. The Phoenix part number is Q2010 (QuickTrim® Polished Stainless Steel Hubcovers for Steel and Aluminum Wheels - emblem style)
I must say that, after reading about some of the members unfortunate experiences with Saddleback, that I have had nothing but good service and both the Service Dept. and Parts Dept seem to go out of their way to "get 'er done".
