Runner is at shop getting some small stuff fixed, will get a measurement when I pick it up. The 2 leaves removed were not insite the spring clamps so I didn't have to reallydisassemble to entire thing. For the rear spring I am not so sure. It would most likely require disassemly of the pack. Now that being said, I would leave the rear springs alone, especially since there is so much more weight in the back the springs will settle when you take them out on the trail. Figure with the top, gear, more sheetmetal windows ect it is a bit heavier than a pickup. A lot of people will go with a 1" taller spring in the rear and it will level out. Instead of initally attempting to level the lift with shackles initially I would get a taller spring, let it settle and then adjust with shackles. Otherwise you may end up with a 9" shackle and well, you don't want that! Just my .02 and I will get some measurements for you as soon as I pick it up.

I am running Bilestein 12" travel shocks,F/R, the rear are getting moved more outboard into a new position as how I had them they became my bumpstop when I removed the blocks and they are angled  /\  . I also have a IFS rear axle that I rotated up for better pinion angle.
Hope that helps
later
