2wd to 4wd?
You'd be putting about $6000 dollars into a swap. You'd have to dich the IFS for leaf springs up front. No you couldn't switch them from a 4WD because the frames are different. The transmissions are different. You have to deal with the transfercase, completele front end swap with a lot of cutting and welding. More work than it is worth. If you need more traction, buy either a lock right locker or an aussie locker.
