Help with Leaf Spring sizing Info for slider fit

I'm in the middle of getting parts together for a 8.8 rear swap and want to have the pinion all set up with leaf spring sliders instead of the rear shackles. My plan is to french the sliders into the end of the frame rails in turn raising the rear spring eye about 4". With that said I have run in to a problem. I wanted to buy a set of slider rather than make them my self but for whatever reason its hard to get measurements from the places selling the sliders. It is mostly listed by application and mighty max is never one of the choices.

Are Mighty max Leaf springs considered "Chrysler type" leaf springs? I'm reading some places this type have rear eye width of 2.5" and in other places it says 2.75".

they are 2.75 inches - smack in the middle of the 2 common sizes - 2.5 and 3". So you could get 3" shackles and shim the spring eyes to center them, or make your own.
