Converting Isuzu 4x2 to 4x4?

Hi, I am obviously new here. I am wanting to convert my 4x2 Rodeo to a 4x4. Does anyone know if the chis will support 4x4 or if I will have to put the body on a different chis. If, so what parts will I need besides, the Front and Rear Axle, Suspension, Transfer Case. I found a frame that has the Transfer Case, Front, Left, Right and Rear Axiles for $650.00 this includes suspension.
