The package gave a fairly wide open application that included 2wd and 4wd from the late 60's to the 90's I can get you a better description when I get home this evening. I bought these for the rear springs on my 84 1/2T 2wd.
You can also go to the Engergy Suspension web site and look at the online application chart. It gives a pretty good view of what fits what.
