Its an F,M & J, k member, pretty much all the same from a 76 & up Volari/Aspen (F body), or the 81-88 5th Ave/Diplomat (M body), or the 81-83 Cordoba/Mirada (J Body).

Had different motor brackets for the slant 6 or the 318/360 small block (only motor choices, your K member is a V8 K member), and some had bigger diameter sway bars and bigger brakes. The famous Dodge squad cars of the mid-late 80s had this suspension.

They gave a nice soft ride (unless you upped for the biggest sway bay). They were not a bad option for updating an old car/truck about 15 years ago. Gene
