Bilstein 5100s - how do I tighten the top nut?

[TexasA&M]

Howdy everyone -

I installed a a leveling kit today along with some Bilstein 5100s. I was working on tightening up the top nut on the shocks and realized that the shaft was spinning underneath the boot. There isn't a nut on the top of the shaft like there was on the stock Ranchos. How did y'all tighten these up?

EDIT - Moved the trac bar question to a new post.

Thanks!
