Great looking work! I also have a Pathfinder, E350. I took off the goofy diagonal front bars and am building crossover steering and a traditional panhard bar. I also contacted a great guy at Lord Industries, who originally built the bushings for Pathfinder. He was able to get me some great schematics and also a tech note from a while back on another bushing they still produce that can be easily modified to work on the coil front axle. I had already made a mold and poured mine with poly, but it may be helpful. Love the full size vans, this is my fourth, your project looks amazing.
