better check some in that era were 3" wide springs . and dodge was using a 7/16 center pin hole over the more std gm size of 3/8 . can make little slopy to install is all.
our truck are 2.5" wide springs .
yes there basicly universal to a point .
and thay make stuff ride a LOT stiffer. most i have installed for cust that i cant talk out of it later want me to remove them .
