Good god, man - Quite ambitious. As far as the rack, it's not as bad as you make it sound. Especially since you already have half the vehicle torn apart. No welding is required. Getting the upper bolt off the rack can be poopy. I've never had issues with the pressure lines. Use proper line wrenches, bolt juice and make sure you flush the pump out. Once the rack, and/or slip joint is disconnected -DO NOT turn the steering wheel multiple times. Best to just ratchet strap it at prime position. Make sure you count the teeth and center the new rack before hooking it back up. Don't assume it's good from the manufacturer. If you want an upgrade, put some poly bushings in the new rack before you install it.
