I am getting ready to replace my brake system in my 82 K20. It is a daily driver so no lift but I may give it a small lift down the road. Since I may get a lift on it someday, I want to go ahead now and get longer lines. makes sense, right 2" to 4" lift would be the possibilities... What off the shelf part numbers do you know of? Or what other applications have a brake line that will work but are longer than the k20? My K20 is the 8600 GVW version so the braking is suppose to be different. The rears are 13 X 2.5 and I think the fronts may have a different calliper. Don't know for sure but it may make a difference.
