Updated Spring Install DIY in all previous posts to Rev.2, posted again below. SIGNIFICANT updates. I had to correct my upper spring pad orientation this weekend and it gave me the chance to go through the DIY. You can now scan the CHECKLIST to ID most of the tools you'll need as they are in yellow highlight. I also learned a bit more about the ISTA spring pad orientation/coding, as well as reassembly order.
