good luck, the front geometry is different between the 2WD and 4x4, you will be on your own for alignment. If you want a frame swap and keep 2WD, your best bet is a new frame. If you just want IFS, go with an IFS kit.
If you keep it 4x4, you can go with a ford explorer rack and not have the radiator to steering box interference that plagues the S-10 swaps
