Well, I caved and called the pool company. Took two of 'em w/me helping. We got it on, but they said it was the hardest one they've ever done. Damn thing's only 8 mos. old or so. A longer bolt would do the trick. All I know is, when I reopen (I don't close myself, I have no interest in blowing the lines, nor storing the tool it takes to do it properly) I will make darn sure that spring bolt doesn't come off. I'll shimmy it all into place. Either that or get a longer bolt between now and then.
