Just reclutched a d22 with zd30 and some gearbox as patrol. Done it on a hoist and bought a gearbox jack . The box is a heavy sucker alright but with a gearbox jack it makes it a lot easier. No need to remove transfer case and done the whole job in a big day with minor assistance. Remember the torsion bars took a couple of hours on their own which patrols dont have.
