Best way to drop my truck ?

[RShaips]

I have a 67 Shortbed with a 71 frame ,so I have disc brakes in front.What I want to do is to drop the front 2-3" and the back 4".I thought I would use drop spindles in the front and springs in the back. Will my shocks need to be relocated in the rear ? What about just putting drop springs in the front without the spindles ? I kinda like the idea of putting air bags in and just running lines out where I can adjust them without having a compressor in the truck.If I do this should I also have drop spindles ? A lot of questions..I Know .But who else to ask ? Thanks
