6" lift might clear maybye a little trimming .
look at
www.offroaddesign.com for bolt in 4x4 cross members .
also
www.diy4x.com has b52 kits that you can bolt in to make it 4x4 on the front fairly easy .
and fyi the front hanger for the rear leaf springs is 3" shorter than true 4x4 version . the riviot holes dont line up for a bolt in swap . so do a 3" block or 2.5" flip kit from offroad design or diy4x on the rear .
otherwise the only other problem is you need a 4x4 trans crossmember or fab one . unless your doing a divorced t-case .
being 2wd already your setup steering box wise to do a bolt in crossover steering kit .
hope this helps and keep use posted with pics .
