allright, here's what I'm lookin for.
The distance from the center for the bump stop to the factory hole in the frame for the shackle - vertical and horizontal distance. Hope that makes sense.
I still have the front section of my frame from the bump stops forward but I didn't take the measurement how far back I had the stock shackle. I was pretty happy with how the spring was setup so I'd like to do pretty much the same distance again.
