The universal joints are not the same size on the N/A vs Turbo driveshafts. The Turbo U-joints are larger, so you cannot simply swap yokes or differential flanges on the driveshaft.

Z31 Driveshaft Information[edit]

The 1984 to 1989 300zx cars came with six different driveshaft configurations depending on body, transmission, and engine. The reason for the differences is each Transmission has their own unique slip-yoke on the driveshaft, and length of the drive shaft will vary per the body configuration.

Z31 Driveshaft Types[edit]

Below is a list of the different driveshaft configurations used in the Z31 chassis:

Driveshaft Type Notes
Automatic 2-Seater Used in all 2-seater automatic models
Early NA Manual 2-Seater (71C) For early production naturally aspirated manuals
Late NA Manual 2-Seater (71C) For later production naturally aspirated manuals
Early Turbo Manual (T5) Used with early Borg-Warner T5-equipped Turbo models
Late 87+ Turbo Manual (90A) For late Turbo models using the FS5R90A transmission
Automatic 2+2 Used in all 2+2 automatic models
NA Manual 2+2 For naturally aspirated 2+2 manual cars

The universal joints are not the same size on the N/A vs Turbo driveshafts. The Turbo U-joints are larger, so you cannot simply swap yokes or differential flanges on the driveshaft.

Differential Companion Flanges[edit]

Style Description Part Number
Early Style Rectangle Bolt Pattern 38210-Y0800 (No Longer Available)
Late Style (87+) Round/Square Bolt Pattern 38210-10V00 (No Longer Available)

You can swap the differential companion flange on the differential relatively easily with a steering wheel puller. Be sure to re-torque the pinion nut to 137–144 ft-lbs after swapping the flange.

Slip Yoke Measurements[edit]

Measurement Value
Length of Slip Yokes 4.125"
FS5R30A Diameter 1.625"
FS5R90A Diameter 1.5"
FS6W71C Diameter 1.375"

Automatic Driveshaft Information[edit]

There were 4 different driveshafts used in automatic transmission models. They varied based on body style and model year. Below is the breakdown:

Model Year Drive Shaft Length (Center-to-Center) Differential Companion Flange
2 Seat 1984–1986 Coming Soon Rectangle
4 Seat (2+2) 1984–1986 34.75 in (882.65 mm) Rectangle
2 Seat 1987–1989 Coming Soon Square
4 Seat (2+2) 1987–1989 34.75 in (882.65 mm) Square
