You could probably do air shocks on the back with like a mono ( the biggest leaf spring ) setup or something , though I wouldnt recomend it .
though this is old ,
You will need drop i beams,bag brackets for ibeam ranger .. for the front OR a front clip conversion from a newer ranger or Mustang 2 for the front . Personally I like the mustang 2 swaps there just $$$.
An I highly doubt you could get a GOOD shop to do a bag job for $2000 , maybe $2000 + , Plus parts .
