I use 2 screw drivers, one long one medium.
Hook one end of the spring into its spot, then stick the screw driver through the other hole and put then end of the screw driver behind where the other spring hook is going to be.
Use the screw driver as a lever.
the spring might just slide down the screw driver or it might need to be pushed down by the other screw driver.
That also works for clutch springs.
