Although I don't have one to offer, it sounds like you're looking for the wood-trimmed steering wheel off of a 1998 "Collector's Edition" Mark VIII. Often just called the "CE steering wheel"
Those cars had a pretty desirable wood shifter as well, and a slightly different finish on the woodgrain bezel that surrounds the stereo and shifter.
Because they didn't make all that many CEs, it is a relatively rare part. I have seen plenty get parted out on these pages over the years however. There's definitely hope that one is out there for you.
