Jason, going to try rubber bushings for the same reasons the OEM's do: less maintenance, less suspension friction (good in a light weight car like this), and less cost! Since my lower A-arm pivot doesn't have to "twist", I can use a stiffer bushing to keep the radial stiffness high (though not as much as PU). I've done the "wooden mockup" thing too, so I know what that's like! I solved the steering U-joint problem with wide spaced A-arms allowing the rack to sit closer and further forward on the pan. The tie rods are at a slight angle in the top view, but not bad. Since T-III knuckle steering arms are bolt-on, they're easily changed or shifted to adjust the Ackerman. With the second ujoint inside the steering tube, you'll need to put another through hole in the firewall, something I also considered
