Searching for Mk1 Diff parts

[player1tv]

Hi, I have and Australian built Mk1 - straight 6 Manual 3 speed.

It runs a 4.63 diff ratio diff and is revving its titties off at 80-90kph. 6 Stud wheel, full floating axel ( i think)

I'm after the parts to change to change the ratio, anything 3.4-3.7.

As we have barely any vehicles in Australia this is quite hard to find. Hoping someone from the Mother Land can save me.
