The rubber boot might still be available from Nissan, I know I purchased mine from Zcardepot and it came in a Nissan bag, I've since binned the bag when I fitted the part so can't confirm the part number but here is a link.

Interesting that you're missing the end cap. It's basically a cap tapped in and then punched (in 4 places I think, 12, 3, 6, and 9 o'clock position) to retain it.
