Just like it says. I have a l98 tpi on a crate 350 going in my 94 s10 blazer and im almost done. But i need to get that damn spring off the throttle body to replace it because its shot. I know someone said to take the 4 little screws out of the blades and grind off the end of the shaft. But the thing is i can find a torque driver that fits in the screw. What should i use? Let me know, matt.
