It all depends on how low you want to go. No matter how you lower it your alignment will be affected. I would lower it using drop spindles and loosening the torsion bars. There are kits out there for the drop spindles. You will have to go with disk brakes if you get drop spindles. Try doing an advanced search for torsion bars or drop spindles under the search menu in the menu bar. It is right under the google search window when you are logged in. There are so many threads on this that you should be able to find what you are looking for. In the future you will be better off asking your questions here http://67-72chevytrucks.com/vboard/forumdisplay.php?f=6
