What is this mopar ?

I spent some time in Mexico 20-30 years ago and I saw some pretty cool mopars down there. Dart gt 68-9 were common. A Demon was called a roadrunner I think, Dart swingers had that swoopy rooflines, can’t remember any e body’s but tons of a body’s.
Mostly stick cars, and 318 many had 4 barrels. Rally dash in kilometers.
I thought of digging one up, and leaving at a condo in the Yucatán
