yeah 5x108 or something silly (european) like that.

Pretty easy to have the hub and discs redrilled to suit.... same goes for the snout flange.. redrill it to suit the stock tailshaft.

so the initial price plus the stud pattern conversion ends up being the same price as a toyota diff?

when you say toyota diff, which one are we talking about? and does it have disc brakes? and how strong is it?

My diff will total around the $250 ready to bolt in....

BTW, if anyone is interested, i am selling the r31 disc brake diff for $80 as i no longer need it.

ok r31,commodores live diffs are the same borgie 70 series now n/a vl's,ford falcon xf's have 25 spline so do pintaras. Skylines,farmounts,farlanes have 28 spline same as the vl turbo/commie v8 diff

sigmas,scorpions have a borgie 70 series diff the same as a st141 it's a smaller housing so the diff center out of anyting mentioned above^^^ r31'ss,commies etc wont fit there far to large for the smaller housing

ok for lsd's ummm all ford fairmounts have lsd's and farlanes i do believe that they are interchangeable with other larger borgie 70 series diffs, if you want an lsd get a ford one there a 4 pinon and most of the time there all autos and on gas so there've had an easy life

xf farmont has a 2 pinion lsd 25 spline so that might fit in a pinny diff MIGHT is the operative word i have heard of people doing it but never conformed

ea farmont up is 4 pinion 28 spline

if your looking at getting axles or a diff center from a v8 commie becarefull of vb-vc's with 253's becasue they had inline 6 running gear

i think that it's

edit: oh and i think that sigma,rona diff are 2 pinion

my diff;

$100 for the MX13 diff
$50 for disks off a st141 (didnt end up using though)
$15 for oil
----------
$165 total

or, add $220 for the MA61 LSD

also note that NO tailshaft modifications were needed....just used one from another toyota

no re-studding either
