Lowering and disc brake conversion

[dagnabbitt]

I am wanting to lower my 1970 swb, and while I am doing it I figure I ought to go ahead and upgrade to front discs and 5 bolt.

I am wondering what the best kit out there right now would be. A year ago if I asked this question everyone would have said ECE, but now I just don't know which company to go to.

Looking for both springs and spindle to get at least a 4" drop in the front. My rear is coils so I should probably be able to achieve the 5" drop there with just shorter ones.
