Thanks for the compliments! The front axle was built by G2, so no sourcing there. The knucles are the same as factory Dana 30/44 out of a YJ/XJ/TJ. As for the steering, it is a full crossover system using heim joints. I got the kit from RuffStuff Specialties and had to cut, bend, and weld it. It just comes as a basic builders kit. I really like how it steers, as there's no play in it while steering. Unfortunately I learned the hard way that you've got to pay a bit more attention to keeping the heims clean. I wore out one of the Teflon sleeves in the joint and there's a bit of play in just that joint.
