I have a 4 inch suspension lift but I would like to raise her up a little more. Would a body lift be the way to go.How long would it take to install a 2 inch body lift on a 86 K5 if I had a the tools needed. (Is this job a Ballbuster) Will there be a gap where the steering coloum goes through the dash area? Do I have to extend any cables if so does that stuff come with a body lift kit. Whats the best one?
