rigger-
I have total simpathy for you. I had my front springs rearched with a new secondary main spring added. I can't really blame the spring shop because when they asked how much lift I wanted I said "max it out".
To answer your question about the spring length, I don't know if you need an exact number. Just take a look at a decent sitting wagon on reasonable springs. The shackle eye is normally straight down and slightly foward with weight on the springs. That's your number there, whatever that distance is. The thread below was my most recent booboo.

A lot of great thought were posted to my reply and hopefully you'll get the right help too. I'm going to try playing with a dual shackle setup in front, kind of like a revolver, minus the revolving. It may not work. One decision I have made is I am not moving any spring eye mounts. If all else fails I'm just going to have new main springs made the correct length (means paying for new bushings again) and swap out the overarched ones.

Good luck Ryan, hope it's not your daily driver.
