In need of some help I bought this blaster few years ago it’s had slightly bent upper a arms and I want to replace them but it’s not the same ball joint as I’m seeing everywhere , I have other complete and rolling blasters and they all have the a arm bolt going through sideways with nut on the end , mine however is more like a car where the ball joint is a stud and the nut screws on the bottom pressing the arm to the knuckle
