For bolt-in ability, it's a tiny bit narrower than the D35 but it's not much, less than an inch on each side. You won't even notice the width difference (I don't on mine).
You'll need some sort of spring perches for it, you can reuse the ones you cut off, but it's less work to get new ones. Ruff stuff specialties (ruffstuffspecialties.com) has an 8.8 swap kit that comes with them and shock mounts, u-bolts, u-bolt plates etc. It's $110 plus shipping but the pieces individually add up. You could piece it together but U-bolts alone will cost around $40. YOu also have to have the flange adapter.
FOr mine, disk brake version, I also needed some pieces of hard break line, I think I used an 8" piece and a 2-3ft piece. and then a second explorer passenger side rubber brake hose. I reused my Dana 35 axle vent tube/brake line block assembly.
