I like both the sag conversions (Chevy and Scout) but with the scout I was worried about the spring smashing the pitman under compression with a hi-steer. Plus like mace said you have to cut the fender apron.
A minus with the four bolt is you have to cut a large hole into the cross-brace and bracing and plating is definately reccomended.
To throw .02 in, on my current 40, I went with Luke's kit from 4x4 labs and it is extremely stout that comes with joints, plates (both sides inner and outer) with spacers already in for the sag box making for a painless install. Plus the steering shaft is made of hexaganol stock with matching u-joints to help eliminate slip. Definately recommend this kit for the four bolt.
