There are numerous posts on this topic. I will share with you what I did because I retained my original hubcaps. The rears will bolt right up, I used wheels off a 1991 Chevrolet Suburban 3/4-ton. The fronts will not clear in most cases without work. I modified my steering arms and tie-rod ends for clearance. Search through some of the posts for other ideas. PM me if you want all the details on how to attach the hubcap clips and modify the front end pieces. Here is picture link you can see my caps/truck.
