Re: 40 series diff ratios
90% are 6 stud ,only 78,79,100 and 200 series are 5 stud. 85% are 4.1 ratio ,14% are 3.7 ratio and if you are really lucky you can get 4.3 ratio out off the late model 79 series pickup.( all % are approx ).hope this helps cheers sig

Re: 40 series diff ratios
Where in NZ are you?
I have a few diffs heads lying around if you are in need of one.
I'm also looking to sell a whole 60 series cruiser rear diff with 4.11 open diff head in it and spring pearches welded on top of diff housing for SOA if you were interested.

Tires are like boobs, they always look big until you have played with them for a while, then you just want a bigger set.

The Landcruiser has a fully floater in some trucks which has the axle protruding out from the drum, but some cruisers have the semi floating axles which are flush with the drum and has circlips in the diff nugget to hold the ales in.

Re: 40 series diff ratios
will either set up be easier to do a disc conversion on or would they be very similar?

The fully floater would be easyier to do the disc conversion on. Ive also got all the parts to put discs on a fully floater if you need them

I'm a bit far away for you dude. Would be easier to find one in the sth island.
For a full floater with an open diff head you should be able to pick a rear 60 series one for $300 or say $650 for an 80 series (just estimates to give you an idea).

Re: 40 series diff ratios
anyone got one of these for sale??
