nah i meant the inside diameter of the axle housing, as too obtain a tube to slide inside the housing were the weld join will be. so i need an exact measurement if you have it please.

When i got my r31 diff cut - i asked them to make it 1405mm. From memory stock is 1395mm.

Using front wheel drive offset rims the tyres scrub a little on the gaurd.

Do you mean the inside diameter of the axle tube? If so the tube is 70mm Outside diameter so inside might be around 65mm.

I ran my tape measure over the diff again (sober ) and from disc rotor to disc rotor (not the mounting face's) is 1240mm.

what is the ID of the axle housing R31?

Hope he's a little more acurate with the tape measure than me May be I should lay off the beer but so dam HOT up here

hilux diff is only 1400mm according to a mate of mine who happens to have a hilux

mmm if i can find a Oz supplier of the tomei coupe flares(or keep the IPRA approved ones i have on) i may not even have to shorten, but will have to bring the front out 17mm each side to match.
Either way i have to do some more searching for a diff.

thats without discs, 1465mm with discs

and according to my measurements it needs to be 155mm shorter to be stock 1200 width....which should be 1310mm or there abouts, so that was some nice rough measurements there bundy351

No mate, mine is shortened. I followed PIGDOG's directions pretty dam close and am very happy with the out come.

Found the info, just spent 2hrs going threw PIGDOGS post.

un cut its 1452mm
