? for those with 4x4 burbs

[cheyenne10]

How wide and how many leafs do you have on front end? (mine is 3/4 ton 4x4)
I am trying to spec new leaf springs and I have 2 up front being 3" wide at rear spring eye. Supplier says replacements are 2.5" and my choice of 2 or 3 leaf. I need new shackles and bushings too. These span frame with shackle. Does the leafs on 4x4 pickup mount this way too?

Please help, pics might help.

Also who has torque specs for new body mount/ bushings?

thanks in advance for any input.
