Just a heads up, Bilstein 5100 bushings aren't sized for our rigs. Not the end of the world but you're gonna have to make a choice for the upper shock mount.
1) Mount it on the original mount bolt with some slop
2) order some bushings/sleeves to fill in the gap
3) Drill out the bolt holes on chassis with a 1/2" bit and mount a 1/2" bolt through the upper shock mount.
I used option 3 and it's worked great for over 2 years so far.
