There was a tech article in an 4x4 & off-road or fourwheeler magazine a year or so back that showed the installation of a manual locking hub kit that Dynatrac made for the 2002 and older Rams with the Dana axles. Kit came with new, bigger diameter axleshafts, old-style (re-greasable!!) wheel bearings, spindles, etc. If I remember correctly, the kit moved the front wheels outboard a hair or two. Maybe the article is available still on the magazines' websites if you want to check them out. Also check out dynatrac.com - I think that site lists prices too.
