Dodges that are Plymouth’s and Plymouth’s that are Dodges and Chrysler’s that are Plymouth’s.
Some people refer to them as Plodges. Chrysler made some “hybrid” models over the years. Mixing front ends of Dodges and bodies of Plymouth’s, or vice versa. Combining Dodge and Plymouth panels to create different models. These cars looked like a Dodge from one end, and. Plymouth at the other.
The 71-76 Demon and Dart Sport are good examples. By simply bolting on Dodge Dart front sheemetal to a Plymouth Duster body, making a few taillight changes etc, a whole new car was “created”
(These were also sold in Mexico as Dodge Super Bees.)
This was a common practice for Chrysler from the 50’s on.
The 55-59 Canadian Dodge Regent, Mayfair, Crusaders were Plymouth’s with Dodge front ends.
Some lower priced 57-59 DeSotos used a Dodge body, while the higher priced models used a Chrysler body.
The 62-63 Dodge 880 was a 62 Chrysler body, with 61 Dodge front end. Which is ironic, since the 62 Chrysler itself was a 61 Dodge Polara, with 61 Chrysler front end and new quarter panels. So in reality, the 62 Dodge 880 was a 61 Polara, with new quarters. Confused yet?
(The 64 Dodge 880 was another restyle of the 62 Chrysler/880 body, with 63 Chrysler bumpers. )
The 63-66 Canadian Valiants were Dodge Darts with Valiant front ends.
The 71-76 Scamp was also a Dart with a Valiant front end.
The 74-76 Valiant sedans were Dart sedans with Valiant front ends.
The 70 Superbird was a Plymouth Road Runner body with Dodge Coronet fenders and hood (modified)
The 75-78 Plymouth Fury 4 doors were a Dodge Coronet/ Monaco with Plymouth grille and badges. In fact, 1974 was the end for the true Plymouth B body. When the new 75 Coronet and Fury B body 2 doors came out, they shared one body. Using the Dodge hood, header panel, grille and bumper on a restyled Satellite. So the side styling is like an evolution of the 71-72, 73-74 Plymouth Satellite 2 doors, but with a Dodge sedan hood, grille and bumper.
In Mexico they sold the Diplomat with a 1980 Aspen front sheet metal, and called it a Valiant Volare. (They also sold the Diplomat coupes with a 360 4 barrel 4 speed and called it a Magnum )
The 78-79 Dodge Magnum was essentially a Chrysler Córdoba with its own unique front sheet metal, door skins and taillights, creating a very unique looking car. ( Did you know the Córdoba was intended to be an upscale Plymouth Satellite? But marketing department decided to sell it as the first “small” Chrysler. )
Wagons are a whole story again, with most based on one wagon body that shares elements of Plymouth, Dodge and Chrysler styling, with different front sheet metal.
And then there’s the dashboards and interiors.
Chrysler loved to mix and match dashboards. Here in Canada, we had Plymouth’s with Dodge dashes, Dodge’s with Plymouth dashes.
Chrysler Corporation cars were designed with so much interchangeability, that depending on the market, they could mix and match parts and come up with unique cars for unique markets.
