Why were the wagons banned?

In 67, a low price wagon was offered in both the B body Coronet line and the B body Belvedere line. These two budget wagons were labeled simply as Coronet and Belvedere, and replaced the Dart and Valiant wagons price wise. A V8 66 Valiant 100 wagon was priced at $2515. A V8 66 Valiant 200 wagon was priced at $2630. The 67 Belvedere V8 wagon was priced at $2673. These 67 Belvedere and Coronet wagons were also a lower trim level than the lowest trim level Coronet Deluxe sedans and Belvedere I sedans. It likely didn't make sense to create tooling for an A body wagon when a B body wagon could be sold at a comparable price point. Keep in mind that the competition was getting away from compact wagons as well. '67 was the last year for the Chevy II Nova wagon and starting in 66, the Falcon wagon was a Fairlane/Torino with Falcon front clip.
But, at least in Australia & South Africa, Chrysler's only wagon was the A body, so they did go to the trouble of making an A body wagon when Australia got their own all new redesigned A bodies in 1967.
