Ok, so now that I have decided on an engine and gearbox combination for my 85 datto ute (Series 5 13b turbo), I thought I might actually swap the diff out for a Ford 9" job while I get all the other parts together. Now, what I need to know is, if I am looking around for this diff, what should I be looking for, ie. should it be out of a specific car, does it need to be a 9" that has certain parts, etc on it? I am doing it this way, as it works out a bit cheaper than having a custom one made ready to bolt in. I got a quote for this today and it was $1850 complete and ready to bolt into the ute, add to this another $200 for skyline rear brakes with a handbrake setup.
So yeah, if anyone knows which one I should look for in particular to suit the suspension setup/layout of a datto 1200 ute, information would be appreciated.

Thanks.
