Silent blades...of grass....cut with furious might

Why does this come with so much stuff? Tubing screws etc?..
My friend bought this for his 2003 gmc sierra w/ 4.3l and 2 days before install he wrecked it. Has this kit and wants $150 for it... I'm tempted to get it but why so much stuff?
oh and cant I use my sealed stock box instead of the open top engine air one?
