tornado s30 hop up kit question.
 

I have had my redcat tornado s30 for about 2 weeks now so I dont really know much about nitro cars at all.
I bought the hop up kit and for the steering pieces im not sure how they r supposed to go on... They have the little ball joint thing in the ends but I have no screws for the ends to attach them. So do I have to by screws for them seperate or is there a way they go on and im just blind?
