Looks bullet proof. What does that thing weigh?

I'm not sure how heavy it is.
my friend gave me a hand to put it on the bench before it had the centre in it,at a guess it weights one and a half of the factory 9in,

COOOR!

Looks killer! Me thinks the truck will break apart before the diff does!

This is true! So basically when it's all done, you'll own a solid piece of granite with 4 wheels and a chrome bumper?

Thank you, It came out of a 2004 au ford falcon xr8.
It looks really good mounted under it and with cut and shut I did on the rear chassis it dropped the truck along way,
i will have to look for pic's and I will post up

We don't see to many '04 falcon XR8's around these parts! Guess I'll have to settle for a t-bird or Explorer. Will wait impatiently for those pics, though!

This is the 'gt 500' version of the xr8, but you get the drift!

How about a mustang cobra irs, they are similar to falcon diffs,

Check into the MArk VIII IRS. I just sold the IRS out the Mark VIII that I took the engine and trans out of. I sold it for $150. I couldn't find anybody that wanted it so I let it go that cheap. They are out there if you look around.

This place sells brackets to use the Thunderbird/Mark VIII IRS. You will also have to change the lug pattern to 4 1/2", its a weired 4 1/4" pattern now. http://team321.com/truckirs/truckirs.html
