As I continue with my design and build for a 1966 Malibu 2 door Nomad Wagon conversion, I am choosing to do a stock looking red interior. http://www.stationwagonforums.com/forums/showthread.php?t=29015 I can use door and rear seat side panels from a 2 door Coupe or Sedan but will need the remaining upholstery to be for a Station Wagon. Looking for recommendations on vendors I can check out who carry stock looking Station Wagon interior headliners, seat and upholstery panels and material for 1966 or 67 Malibu Wagons.
Try SMS they are who I used for my Falcon & Mercury wagon seats, door panels, and material for other interior panels. link; http://www.smsautofabrics.com/
I would like to buy the panels and covers I need. Some catalogs that I have checked into seem to not have the right stuff for Station Wagons.
Eckler's shows some wagon parts in their catalog. They specifically list station wagon headliners and rear compartment trim panels. I purchased many Corvette parts from them in the past; they've been around - and expanding their product lines - for many years. http://www.ecklerschevelle.com/
I've used a guy out of New York for a couple of sets of covers. He does nice work and has been very reasonable. He will make them to match your supplied covers, or do custom work as well.

I'll "second that". SMS had an exact match on the carpeting I needed for my '75 Caprice Estate. They also carried an exact match on my upholstery pattern/color AND door panels. Customer service was great and prices were reasonable but not cheap.
I got a headliner for my 1950 Plymouth wagon from SMS. They made it from a swatch of black vinyl I had the rest of the interior done in. If they have stuff for a 50 Ply wagon, they should have what you need.
