Well to make a 60 steer in you're toyota, you may have to build a new tie rod and drag link if you will be tying into that for you're steering. If not then you will need a high steer arm, and just a new drag link. About the Hydro, the only way you will ever blow a line is if you are a cheap ass and use single jacket line, or you have you're lines or fitting's run into harm's way(exposed to moving components, or exposed to obstacles). I'm sure you carry other trail spares, so why not a couple feet of hose and a few fitting's? There are probably 50 people on here running full hydro and of the one's that fall outside of my description(doing it the right way) I bet they haven't had a failure. As far as steering with you're vehicle shut off, yeah, it's no plush job, but I bet you will have better luck steering a dead buggy on 40's, then you're dead whatever with conventional steering.
