everything should be compatable with chevy c-series trucks, providing it is 2wd, so just look those up, and you should be able to find the parts you need.
Here's a pic of my old Suburban that Jenni from MT mag and DropEm Wear has now. This was with a 2" spindle and a 3" spring up front for a 5" drop, and a flip kit and hangers with a bolt in notch like pictured above in the rear for a 6-7" drop out back.
