That was probably the ugliest wood treatment that any Chrysler product ever had. I've seen a few for sale lately. www.stationwagonforums.com is where you want to go, There are a few wagons listed over there that have the same wood treatment on them. All of those are pretty rough, though.
Yes, the big C body wagons need woodgrain in my opinion to break them up visually...otherwise it's too much.
Of note, the 72 Monaco had a dark brown woodgrain as a base for the pattern and in 73 they swapped the pattern to a light brown woodgrain base. Here's pics of a 72 contrasted to the 73.
