For replacement purposes there are only 2 rad fan assemblies.
A small motor 200/300 watt and a large motor 450 watt. You need to use
the right version for your wiring. The fan shroud is also different to
match the motor size. The fan blades are the same diameter, the motor is
different and the wiring is very different.

82-85 200/300 watt small motor.
86-91 2wd not with factory A/C 200/300 watt small motor.

86-91 with factory A/C 450 watt large motor.
All Syncros use 450 watt large motor.
