[BlueJeep]

Check out my build thread for info on the notch. I'm just finishing it up now. Only commercially available notch I found was from airbagit.com.

Those pictures you posted are lowered 6" in the rear, so they have flip kits (or equivalent) based on how they sit.

The problem I see you having is floor space for that massive 14bolt FF axle. I notched mine so that my 10 bolt will not hit the floor, but you have a lot less room than I do. An option to keep it 3/4 ton would be to swap in a 14 bolt semi float axle in the rear, as that is physically smaller and would clear the floor better. Another option (albeit more expensive) would be to put a ford 9" in the back with 8 lug axle shafts.

That blue/white suburban is interesting, where did you find the picture? It has 6 lug wheels, which appeals to me as I've been toying with the idea of swapping in a 99-06 rear axle with OEM discs, maybe even with the link suspension of a suburban/tahoe.... Front 6 lug rotors are available too.
