Lift questions

Looking at lifting my 2nd gen and have some concerns. Looking at doing 4" spindles with 2.5"-3" lift coil springs in the front but the problem lies in the rear. I'm not a fan of 4" lift blocks. I could get all pro 3" lift leaf springs but then how do I get the rest of the lift? Can you use an AAL with the All Pro's. Or could I use the factory leaf springs with a 2" AAL, a 1.5" progressive AAL and a 2" block? What are my options in the rear? Also with this size lift what trimming if any is needed to clear a 315/75/r16. Sorry for being a noob guys

 

Or 2 2" single leaf AAL's and a 2" block? Also what U bolts will I need. Or at least the dimensions of the ones I would need
