shocks are different 2wd to 4wd. You also need to swap the metal plates the headlights bolt to to make the swap - the 83 MMM grille is more rare and worth keeping. The motor will fit regardless of if it is a 2.0 or 2.6 - both automatic blocks are the same narrow bolt pattern - you may have to swap torque convertors to match the 4wd tranny.
