paul I am dealing with the same issues now. I'm picking up some Chevy 63" springs for the rear, and for the front I was going to do pup rears with an addaleaf SOA with shackle to rear drilled through frame. Not sure if I can pull that off though here in MA lift laws are much more strict than in your area I bet. I saw (Tuite) Nick's sas with troop rears up front and I still think that is too much lift for me.

I bought the Skyy manufacturing 63" spring kit which includes shackles, f+r 2.5" spring mounts, hardware, bushings for $115 pretty good deal.

Maybe I will go toy rears up front since they are flatter hope you get some ideas this weekend i will get back to you about what I find out.
