Installing FBO Advance Plate ...help

To answer you original question, the spring wire clip is on inside. It has 2 little wires pointing up, and you need to expand them outward from center shaft. I did that recently and is real b**tch. I took 2 ink pen metal ink tubes to hook the pointy wires. When I put it back together I slipped a small O-ring over groove on shaft instead of clip. I think I see the up-pointed wire tips.
