hey guys, I've just about got all my shit together for my 4a swap in my ksev, but I need some advice on suspension/diff setups.

What I'm going for is a near standard height with a set of coilies up front, with the falcon springs in the rear. I know I need either siera or commodore short stroke shox in the rear but which commodore or siera? What model falcon springs work? I've got a pair of xe lowered kingsprings. Would these work?
I'm thinking about upgrading to a hilux diff purely because I have one already and I don't want to weld or blow my standard one.

What coil over setup works well in the front without putting to much track on?
Does the hilux diff fit ok under a ksev?
Also how much does a t or f series diff fetch these days?

Sorry if I don't make much sense as it's 3am at the mo :s

Peace out hombre's
