Here is what I would do. Swap the drivetrain into the blue toy and do dual cases. Keep the stock gears, weld the rear diff, Aussie lock the front. Build a new front crossmember and mix the rear leaf packs together to build a front spring pack. Grab some stock 90ish model F150 springs for the rear and run them short side to the back. Ditch the bed, and build a small flatbed. Do sliders, but don't bother with boatsides because they are not easy to do on a toy due to the location of the cab mounts. Square driveshafts front and rear. Ditch the bodylift, and cut the floorboard to do the flatbelly. If you plan on beating the thing, build a roll cage or exo.
The 303 tires are for a 16 rim right? Be careful when grabbing junkyard rims, because most of the time 16 rims came off of IFS rigs, and the offset is to much to run with toy straight axles.
