hi all, is there anyone out there that has put a 78 series rear diff in to the arse of there hilux? I have a 89" 2.8 diesel. My biggest problem is, is there going to a ratio that i can use. sorry i dont know what ratio. but i spun the wheel one turn and the tail shaft did 2.
the job doesnt seem that hard i just want to get it right the first time. any help will be much appreciated.

Hilux rear diff= centred
78 rear diff= offset
78 rear diff= 5 stud???
hilux rear diff= 6 stud
Ratio - maybe. 89 2.8's are 4.3, and 78's are 4.3???

It'd be nice for the disks, full float and strength, but I think it might be a fair bit of work to get right - i.e custom centred conversion.

I'm guessing you'd need to upgrade the master cylinder too.

don't luxes have more ratio's readilly available?

Yep

Ive fitted a centred 4.3 cruiser 78/100 series diff centred with Hilux axles and custom rear disc job recently with no probs and they run a massive 9 1/2" crown wheel so you could never hurt one with any motor you could fit in a Hilux.

Ive built over 50 of these rear housings up till now and the 78 diff was no different only the cut out to clear the crown wheel needed to be opened up to clear the bigger crown wheel. Havn't got any pictures only my engineering drawings that ive developed over the years to store all the info for all the different models.
