This article is from the Chrysler-Plymouth-Dodge FAQ, by Dr. David Zatz with numerous contributions by others.
... Chrysler used the components on the Aries/Reliant (K) in many of
its other platforms. These platforms... share similar distance
between the wheels on the same axle, and have the same suspension
design. Most K variants can swap struts (H is an exception).
K derivates include: Laser (pre-88)/Daytona (G), Shadow/Sundance
(P), LeBaron/New Yorker (J), LeBaron sedan (pre-90)/Lancer
(H), Dynasty/New Yorker/Imperial (C), Acclaim/Spirit/LeBaron sedan
(AA). Each derivative has a different wheelbase and floor pan.
The minivan is only loosely based on the K platform. (Executive
and Limousine were low-production extended-Ks, and the CSX
was a performance Sundance/Shadow).
These cars are collectively referred to as EEKs.
