I failed to thank Delaware rider (see his comment in this thread) for his input/insight into installation of the saddle from his own personal experience with same. I'd read several comments from others that found the initial installation to be difficult or nearly impossible, due to some oddity with the thing, so I was naturally skeptical at first. BUT, indeed, by just varying the "angle of attack" initially, it will fit-up and seemingly DOES "work in" and become easy to remove/replace, thereafter, as D. R. told me.
