the centres will bolt in between the 82 and 85 models....
to check the ratio just put it in, turn the wheel once and see how many times the spider gear on the centre turns.

also i do believe that front and rear centres are interchangeable.

yes it is

clean the crown wheel on the outer edge you will find a circle around a stamped to digit number

so far i have seen on different hilux diffs

41=4.11
43=4.33
46=4.55
48=4.88

Yeah this is on the late 80's and 90's crownwheels,its the number of teeth on the crownwheel and 10 on the pinion. The early ones are a bit different(just the number of teeth if you know what i mean.Just count the number of teeth on the crownwheel and divide that by the number of teeth on the pinion and you have your ratio.

I think cruiser discs were all ventilated, thats a solid disc so probably anywhere from 79 till whenever they put vented discs in hiluxes.

Close but it is actually Stamped as 4.1,4.3,4.5,4.8 These are all later model Hilux Diffs.

The early ones will have the Crown and Pinion Teeth Counts stamped on them as Bogan Suggested.

Some dont have anything stamped on them at all so you just count the Crown Wheel teeth and Devide it by the Pinion Teeth.

As that is an early Hilux housing as long as its never been changed it will have 4.88 gears fitted.
