I've been searching unsuccessfully for some details before I start this project, but to preface I have a 1986 LN65 with basically factory suspension which I intend to keep for the time being ( factory leaf + Solid axle)

I went up in tire size from 31 to 33" and now I have a small amount of rubbing at flex while turning, no surprises there.

I've read a popular option to fix this with my setup is to simply move the axle forward on the leaf a little bit, I understand the job but had a few specific questions that I wanted to think about before I dive in.

1: How far forward is optimal? , I heard ranges from 15mm to 35mm..
2: do you put the drive shaft spacer in the diff side or the transfer case side and should it be the same width as the diff is pushed forward?
3: will my factory steering need adjustment or will it be as simple as just adjusting the drag link to center the wheels?
4: whats the best option for relocating the bump stops? move on the frame or relocate to the axle?
