I have an 88 c2500 with a 4" RC lift and need to pretty much replace most of the suspension parts. Anyway, I was wondering if you could put newer style control arms from an nbs or nnbs truck. Both upper and lower of course. I found some from ksp that are made for 2011-18 trucks with a 2-4" lift but I'm not sure that all of the dimensions are the same. I'm only wondering because 1: I love the look of the shiny tubular uppers and 2: if the dimensions are the same or similar then my ball joint angles won't be so bad and not wear out so fast. Any help is appreciated.
