Front or rear? Or both? And what do yo mean by "4link" ? Three control arms and a panhard (track bar)? Or four arms plus a panhard? Almost everything I've seen on first and second generation trucks is three link (plus a panhard). I want to do this myself, but mine would be a mild coil spring set-up with only a few inches of lift (front and rear).
