Mate if you have the correct parts it's a no brainer, in real terms the toe won't even change that much, then you just really want a good wheel alignment to correct the minimal change from swapping drag links. The extra caster can then be given at the same time to make it steer better. Extra caster makes them heavier to steer so it is really only applicable once you have power. Don't go by factory setting start at 4deg positive and go higher if you can, without the wheels hitting the front edge of the arch on turns. If the wheels clip the front edge. They need to wind back the caster bars and then use shims to give it extra caster, having said that, most won't bothered frankly. Personally if you want a good aligmnet get Ozbilt to set it up for you and that will be as good as it gets,or do the whole job
