I have a 1999 Civic Hatchback with the stock D16y7 motor. I'm doing a 98 Y8 intake mani swap, and have a throttle body from a 00 EX. I know i need to swap the rotor and spring from the EX throttle body onto my stock Y7 throttle body, but have no idea how to separate the spring and rotor from either. I have removed the nut from both, but now what? I've even removed the throttle plate from the throttle body, but obviously that has nothing to do with swapping them out. I've pried and pulled to no avail. Please help.

 

pb blaster, and gently pry from behind.
