stormperson: Toe links... I don't know for sure. Since I got my kit in a trade, I don't really know what should have been included in the box. However, the guy that I traded with did include a set of links.
For the front springs (Old School Front End), I found it "easier" to install the "E" clip under the spring first, then allowing the tension of the spring I slid the second "E" clip between the steering block and arm. This held the "E" clip in place, while I used my small flat blade screwdriver to push it onto the king pin.
Rear Axle: This Associated rear axle is really different for me. I really like the left side screw on hub. However, I thought that something was wrong when I saw the diff rings. On my Carpet Knife, the diff rings were keyed ("D" type ring), so that the diff rings didn't spin freely. I don't know if there's any advantage but it seems to make since for the diff ring to be stationary???
