using the 4x2 wouldnt be too bad really... you could use any of the SAS kits out there and it wouldnt be bad.... also with the arch of the 4x2 in the front, you can run hysteer and all that stuff later with less lift as the frame arches higher.... you would be basically retrofitting a 4x2 frame with an sas, and 4x4 conversion, you already have the parts, so you will jsut need new tranny/tcase mounts and the spring hangars really....
