The 78/79 uses a solid axle in the front, and your 86 has the twin traction beam front suspension. To lift the 86, you need drop down brackets for the axle beams, and extended radius arms, or drop brackets for the factory arms. This in addition to the usual springs, drop pitman arm, brake lines, shocks etc. Also, the twin traction beam has a different lower mount for the coil springs, so I don't think the earlier coils will fit, not positive though. Take a look at skyjacker or someones web site and see what they include to lift the TTB, it will give you an idea. I suggest you just order a kit and do it right the first time
