We have about fifty LTD-based "Ford Country Squire"

And there are 150+ named "Ford LTD Country Squire"

Should the "Country Squire"s be changed to "LTD Country Squire"s?

I would say the opposite: shouldn't they be listed without "LTD"?

Hmm, I guess that would make sense in a way. Then I guess you should also rename the Custom/Crestline/Fairlane/Galaxy/etc/etc Country Squires?

LTD should probably be in the name. When I was a kid we had a '70 Ford LTD Country Squire and the "LTD" letters appeared on the front clip. Ford clearly wanted to push that trim level as top of the line.

Since the late-60s and early-70 "LTD" and "Country Squire" go together in the official names. Just look at the badges.
