Wear in the distributor drive gear can introduce play that can retard timing, while worn distributor shaft bushings can result in erratic timing. Both conditions can affect engine performance, fuel economy and emissions. If the distributor is worn, replacement is the only repair option.
When you install the new distributor, line up the vacuum advance in the same direction as the old distributor was pointing, rotate the shaft so the rotor will be pointing approximately in the same location as the #1 spark plug terminal, then slide the distributor into the engine. The angle of the drive gears will cause the rotor to rotate slightly and the distributor slides all the way into the engine. Replace the distributor hold down clamp and nut, but do not tighten.
Start the engine and use a timing light to adjust the timing to specifications (typically 6 to 10 degrees of advance with the vacuum advance hose disconnected and plugged at 550 to 650 rpm idle speed
3.4L 5VZ-FE V6 replacing the previous 3.0L 3VZ-E V6: power: 183 hp (136 kW), max horsepower: 4800 rpm, torque: 217 ft lbf (294 N m), max Torque: 3600 rpm.
I believe it will fit.
