lets go for another alternative answer!

petrol are 4.30 or 4.56, possibly the soft tops are the 4.3 but I can't confirm that 100%


all of the turbo diesels I have seen are 4.875

with the bunderras it depends on the wheel package that was
fitted by the factory
std had 4.3 4.5
wide wheels were 4.8
have checked dozens of these to verify this
spft top and hard top make no difference

So Going by this my Bundy RJ70RV 22R petrol would be 4.8's or 4.3's??

The build date is 04/1985

I would jack the car up and do the Tailshaft turn thing but Im about 4hours drive from it and wont be back there for a month!

Some help would be great, if anyone knows.

Gearbox; 5-speed manual and is the same as the Toyota Hilux G52 5-speed. The gear ratios are as follows;

1st 3.928:1, 2nd 2.333:1, 3rd 1.451:1, 4th 1:1. 5th .851:1, reverse 4.743:1

Transfer Case; The transfer case is the same as the Toyota Land Cruiser split transfer case and is part time 4WD with a 34mm idler shaft and a low range ratio of 2.276:1.

Differential; The differential ring and pinion tooth count is 43/10 giving a ratio of 4.3:1.
