So very much more than just K, though a lot of interchangability.

Original K Reliant and Aries and the Lebaron K. Engines were 2.2 Chrysler built motor and 2.6 Mitsubishi motor. Produced through 90.
84 brought turbocharging to the 2.2.
84 also brought the S bodied minivans with 2.2 and 2.6, but no turbo.
Also, a stretched K or "E" Class was added and an even more stretched K base Limo...
Daytonas were added in 84 or 85 as a G body. A very refined version of the K car.
85 introduced the 4 door H body Lancer/Lebaron GTS, basically a stretched G body. Ended in 89.
87 brought the extended length minivan, as well as the 3.0 V6 Mitsu motor.
87 brought the Shadow/Sundance as a P body. Depending on year, 2.2, 2.2 turbo, 2.5, 2.5 turbo, 3.0 V6. Last year was 94
87 also brought the J body Lebaron Coupe and ragtop. Add the 2.5 turbo and 3.0 V6 too.
88 saw the A body Spirit and Acclaim, with 2.5, 2.5 turbo and 3.0 V6.
89 and 90, the short wheelbase minivans got the 2.5 turbo as an option. (Ever see a minivan dragrace?)
91 saw the minivans get a facelift, through 95. 96 saw them turn into to overweight jellybeans...
93 saw the end of the Daytona and the A bodied cars. Also, 93 saw the last of the turbo cars.
I won't even discuss the Shelby cars of the era... Yes, Shelby worked with Dodges too.

Does this help?
94 saw the end of the P bodies.
Some 95 Lebarons were produced, all were convertibles.
