Replacing pickup sensor
Ok im in the middle of replacing my pickup sensor, i have the cap off i have the rotor off and i have the little metal piece with the two flathead screws in it off. Now my problem is i cant get the little metal piece below the piece with the flathead screws off so if somebody could help me that would be great thanks.

STATOR ASSEMBLY REPLACEMENT
Carbureted Engines
Disconnect the battery ground cable.
Remove the distributor cap.
Remove the rotor.
Unclip and remove the upper distributor body.
Remove the retaining screw and remove the wire harness from the distributor.
Using a small gear puller, remove the stator from the distributor shaft. As the stator is pulled up on the shaft, take care to hold on to the roll pin so that it doesn't fall into the distributor.
To install:
Place the new stator on the shaft, press or dive it down slightly, insert the roll pin and drive it into place inside the stator.
Using a deep socket, or similar tool, drive the stator down until it bottoms. Check occasionally to be sure that the roll pin stays in place.
Install the wiring harness, upper body, rotor and cap.
Fuel Injected Engines
V8 ENGINES
Remove the distributor assembly from the engine; refer to the procedure in this section.>
Remove the ignition rotor from the distributor shaft.
Mark the armature and distributor drive gear with a felt tip pen or equivalent, to note their orientation. While holding the distributor gear, remove the 2 armature retaining screws and remove the armature.
Do not hold the armature to loosen the screws.
Use a suitable punch to remove the roll pin from the distributor drive gear; discard the roll pin.
Position the distributor upside down in a suitable press. Using a press plate and suitable driver, press off the distributor drive gear.
Use a file and/or emery paper to remove any burrs or deposits from the distributor shaft, that would keep the shaft from sliding freely from the distributor housing. Remove the shaft assembly.
Remove the 2 stator assembly retaining screws.
Remove the octane rod and screw.
Remove the stator assembly.
Inspect the base bushing for wear or signs of excess heat concentration. If damage is evident, the entire distributor assembly must be replaced.
Inspect the base O-ring for cuts or damage and replace, as necessary.
Inspect the base for cracks and wear. Replace the entire distributor assembly if the base is damaged.
To install:
Position the stator assembly over the bushing and press down to seat.
Position the stator connector. The tab should fit in the notch on the base and the fastening eyelets should be aligned with the screw holes. Be sure the wires are positioned out of the way of moving parts.
Install the 2 stator retaining screws and tighten to 15-35 inch lbs. (1.7-4.0 Nm). Install the octane rod.
Apply a thin coat of clean engine oil to the distributor shaft below the armature. Insert the shaft into the distributor base.
Place a 1/2 in. deep well socket over the distributor shaft, invert the assembly and place on the press plate.
Position the distributor drive gear on the end of the distributor shaft, aligning the marks on the armature and gear. Make sure the holes in the shaft and drive gear are aligned, so the roll pin can be installed.
Place a 5/8 in. deep well socket over the shaft and gear and press the gear until the holes are aligned.
If the shaft and gear holes do not align, the gear must be removed and repressed. Do not attempt to use a drift punch to align the holes.
Drive a new roll pin through the gear and shaft.
Install the armature and tighten the screws to 25-35 inch lbs. (2.8-4.0 Nm).
Check that the distributor shaft moves freely over full rotation. If the armature contacts the stator, the entire distributor must be replaced.
Make sure the back of the TFI-IV module and and the distributor mounting face are clean. Apply silicone dielectric compound to the back of the module, spreading thinly and evenly.
Turn the distributor base upside down, so the stator connector is in full view.
Install the ignition rotor onto the distributor shaft. Install the distributor as described in this section.
