To get away from the windup of the leafs on hard acceleration I add or delete an extra leaf or two, sometimes flipping one over upside down to counter act the forces. make the rear end stiff but also keeps the car straight out of the hole and no ugly pieces hanging down under the car.

The Datsun 1200 Nissan Competition Schematic book has all the blue prints for the track rods and panhard rods if you can find one of these books

you guys are wasting your time an money with this setup. Talk to John Taylor about his springs and axle tramp will be gooooone with loads of traction.

for all you people who have got your r31 diff cut down and modified to suit the 1200 i just wanted to know around about how much would you expect to pay for this?

When I get mine back I will re-open this thread and let you know, until then I dont really know.

Cheers Mitchell.

$500-$1000 for the mods (Add $200-$700 depending on which bw78 diff you choose)

who is John Taylor? does he run the R31 diff

think i might stick with the hilux diff then.

I got the borg warner diff back today, here is what was done to it.
one axle was resplined
it was shortened, two inches narrower than original (to suit the wheels I have, so I dont need flares)
all the mounting brackets were taken off the original unit and welded onto this one (trailing arms for the four link and coil bases)
All that was $1060, and they supplied the diff. I am going to use the skyline centre until it breaks and then probably go with an LSD, maybe.
Not that you 1200 guys will need to worry, but they also stuff the trailing arms in making the jig so make sure you get some more, but if you go to Aussie Diffs they have a sunny jig made up now, thanks to me.

Here are a couple of shots I got of it before it went in.
The old dirty one is a standard sunny diff, notice a slight difference in size
