so they more or less "fell in"easy,maybe some sealant might help them seal?
They didn't exactly "fall in" place, had to be pushed in, but the fit was not as tight as normal seals you have to bang in place with a split ring.
Evidentally that is the way they are supposed to fit, as the instructions say they are to "float" in the seat area, and need at least 0.5mm clearance between the seal and clip, and 3-4mm space is ok.
OF COURSE, I didn't read the directions till I finished installing the first one, and it felt too easy!!
