For me the tremec on stock final drive and .82 or .83 what ever it is was just about right for a Cossie.
Also look at the speedo drive as one is electric and the other is cable from mem.

23 mph per 1k
About 180 ish
I've got a didgital speedo that runs of the front wheel
So that will save ME, at least the bother of cables.
Good call though for other people wishing to convert to the tko,
If you're considering the T56, the drop from 4-5 and 5-6 is huge unless you get one with the 0.83/0.63 5th and 6th. ( there are a few variations, but they're mostly around there. )
The tall 0.74 and 0.5 5th and 6th are huge and make almost any gearing setup awkward.
It works ok on a big V8 with lots of torque though.
Short diff and short overall gearing may help this, but I'm sure it still wont be ideal
Most boxes can run either cable or electric speedo sender, although the T56 is normally electric, so to convert for cable will cost.
I'd guess the TKO could be ordered with either.
The newer TR6060 is regarded as a much better box than the T56, although again comes in a variety of ratios and fitments.
