locating leaf spring sliders

Looking at this picture, it looks like you have the slider 4 inches from the rear mount to the front of the end of the roller stop. Is that correct or am I looking at it wrong?

I‘m trying to get the slider located properly with no weight on the springs.

If I have your numbers wrong, how far forward should the end of the front of the slider slot be from the vertical mount??

TIA

The measurements are just on the bracket. The bottom plate of the bracket is 4" long. The front mounting holes for the slider are about a 1/4" from the end of the plate. The rear mounts of the slider are inside the rear outrigger of the frame. And mine could probably be mounted a good 1/4" to 3/8" further back, based on where the spring eye ended up after my springs settled.

So, just by the math I would say on the AFCO's at least you'd want the front mounting holes of the slider about 3 1/2" forward of the front face of the spring outrigger. At least for the AFCO springs I'm running...
