The 1000 ute came with a 4.11 diff ratio. Good for faster acceleration and carrying loads
120Y came with 3.889 diff ratio. Slower acceleration but reduced revs on the highway (meaning better fuel economy and less noise)
"120Y diff" can mean several different things: You can peek under the car to find out
* swapping the diff head. The H150 from a 120Y can be swapped for the H145 that comes in the 1000 & 1200
* swapping the rear axle assembly. Is possible, but unlikely as the 120Y axle assembly is 66mm wider. would need high-offset wheels and/or fender flares -- and the leaf pads need to be moved
* 120Y australia-assembled used a Borg-Warner 68 diff. Can be swapped same as the Japan-built 120Y rear axle assembly, but the diff head by itself won't work in Japan axle
gear carrier assembly ("diff head" or "pumpkin")
rear axle assembly
Borg-Warner: removable back cover Hexagonal with 8-bolts (Salisbury type)
Japan: welded back cover with no bolts (banjo type)
If you have the Japan axle, you can tell by looking if it's a H145 or the stronger H150
H145 flange is scalloped (not a rectangle)
H150 flange is rectangle
