I made a chart showing my truck throughout this process with different suspension set ups. This shows the stock height, up and down with just the Porterbuilt Stage 1 kits, up and down with the stage 1 kits and the McGaughy's drop spindles, and up and down with everything plus the notch. Hopefully this helps someone else out when planning their set up.
Here's a link to the full size version:
