I did mark it, I guess just not that well. It seems pretty close to the end to me, although I think I have it back to the place that I marked off. I guess the best way to explain it is that I can't see or even feel the splined part coming through the hole in the bottom, if that makes any sense. It did move up a bit when I got the rack torqued up. I think I will climb back under there tonight and try to get it on a little further. I just don't want it to bind or something if it is too tight.
