Diffs are interchangable. Only problem might be flanges for driveshafts dont match up but they can swapped to suit.

60 diffs are wider, you will have trouble getting a front 60 diff in sprung under. Some options available with hilux hubs etc.

im still keeping the 75 series housings, only want to change the centres around and if they are interchangable?

Yep, they are interchangable. Like I said, flanges might be different.

78's have a smaller front diff, obviously these aren't.

Sorry mate, gave you a bum steer, high pinion won't interchange with rear.

thanks for all the advise its been a great help, just pulling the spider gears out of the 60 series diff to install a lock right ,question is theres 2 shim/ spacers on the large spiders the ones the axles go into ,should i be reusing these on the lockright??????

Out of curiosity, what year/month did 75's change to HP front? I understand early HZJ75's still had the low pinion 9.5"??
