yes you can fit a late 75 and 80 series into the rear of a Hilux
80 series ratio is 10x41 = 4.1
75 series ratio is 9x 37 = 4.111
open center will go straight in with no mods
If you want to use the 80 series Factory ELECTRIC LOCKER you have to modify the housing slightly
I have been using the 80 series front locker in the rear of my Hilux for nearly 8 years

If you want to use the 80 series ''electric locker ''you have to modify the housing
NOTE I DO MENTION TOYOTA 80 SERIES ""ELECTRIC LOCKER " NO MENTION OF DETROIT OR OTHER VARIANT

You have to modify the diff axle housing where the where the center or pumpkin or what ever numeral names the have
You have to cut a piece out of the housing weld and grind a flat surface for gasket contact then drill and tap 4 holes

Installing a front (high pinion) diff http://home.4x4wire.com/erik/diffs/hipi ... ectric.jpg in the Hilux rear axle does give you ground clearance. However the front diff's ring and pinion gears [/u]should be[/u] reverse cut. Installing the diff in your rear axle means you're applying torque to the weaker (coast) side of the gears. Same action as driving the differential in reverse all the time.

A better option is install the high pinion diff up front (in a solid axle) and a 22RTE/V6 rear diff in the back axle housing. See this pic for the difference in the rear diff housings (4 cyl and v6. The v6 is in the background).http://www.4x4wire.com/toyota/faq/parts/3rds.jpg
Here is a pic of the high pinion front diff. http://home.4x4wire.com/erik/diffs/hi-pinion.jpg

If you want the toyota electric lockers. Look here: http://www.4x4wire.com/toyota/tech/electric_locker/

I'll have to locate the URL for the article I found to install the high pinion electric locker in the front of a solid axle.
