Two choices: use the special distributor drive puller, or take the engine completely apart. I recommend the puller.
The distributor is a single unit. Set the engine to top dead center. Make a witness mark on the distributor body and the engine case to reassemble and re-align the unit. Remove the distributor clamp holding the distributor in place. Remove and mark the wires. Pull the distributor straight up and out of the engine case. The shaft is keyed and should be in the body of the distributor. Reassembly is the reverse procedure.

Remove the clamp for distributor. Remove distributor, making a note how it is orientated for #1 position. Also check which way slot in drive faces for reasssembly. With a strong magnet, reach down in distributor hole and allow magnet to pull up on distributor drive gear...if it is reluctant to move...rotate drive gear back and foreward with a screwdriver in the gear center, while pulling up with the magnet. Drive also turns the oil pump and it may need a slight engine turn to free it up..
depends on the car. GM distributors require removal of the distributor from the engine. Then removal of the drive gear at the bottom of the distributor by driving out the pin. Remove the shaft through the top of the distributor Unplug and unscrew the pick up, install new. Reassemble, preferably with new retaining pin. Re time engine ignition.

Remove the distributor from the engine by completely. Record the postions of the rotor and base BEFORE removal. Drive out the pin at that holds the drive 'gear' ontot the distributor shaft. The rest of the distributor disassembles from the 'outside'. Several bolts hold the coil assembly in place. Replace all of the O-rings when re-assembling.
The 4.3L V6 GM engine does not have a timing belt it has a chain, and it does not directly drive the distributor.
You can't do it, unless you want to pull the engine and split the case. The puller is the only way to grab the drive pinion.
To dismantle the distributor already off of the engine: 1. Mark the position of the drive gear on both the gear and the shaft so they can be put back together in the same location. 2. Support the body of the distributor and using a suitable drift punch the drive pin out of the gear and shaft and remove gear. 3. The shaft will now come up through the distributor housing, and is essentially taken apart. 4. To remove the pickup coil remove the clip that holds it in place and take it out. 5. To remove the ignition module take out the screws.
Disconnect the battery. Remove the air temp sensor, air filter hose, and accessory drive belt. Drain the radiator and remove the hoses from the water pump. Remove the distributor cap and rotor, and replace with new ones.
The easy way is to replace the entire distributor with a remanufactured unit. The hard way is to mark position of distributor rotor, remove the distributor from engine,reome cap & rotor, remove drive gear from the bottom of distributor , slide shaft up & out, remove pick up.reverse steps & reset ignition timing. IMPORTANT TO MARK LOCATION OF ROTOR BEFORE REMOVAL
It depends how the distributor is driven, if it is an ohv engine or the distributor is driven by a shaft in the side of the cyl block, the distributor should be driven by a helical gear. To remove this you loosen the pinch bolt at the base of the distributor that clamps it onto the engine, give it a wiggle side to side and just pull until it comes out. Obviously remove the wires and plug leads first, noting the order the leads are in and replace them EXACTLY as they came off, also mark the body of the distributor to a mark on engine block so when it is re-fitted, the marks line up for easy timing. Hope this helps
