Thanks for posting those for me Craig!
I got the work done at a place called Diff Technics in Sydney. Con was very helpful and the result looks great.
It is a 3.00 ratio 9" centre with LSD, new everything inside aluminium pinion support, aluminium case, GTHO diff yolk all ready to hook up to my Jag IRS, (currently having outboard brakes fitted to it).
This was the only way I could think of to hold the power of the big block and have IRS as well.
As far as cost goes
it was roughly $5000.00 Au, but at least it will be strong enough!
Andy.
