slant gears help

Unfortunately for you USA guys, you didn't have BW diffs in your Valiants/Darts...we did....and there are heaps of ratios to pick from, from other Oz made cars with the same type diffs.
I've got a set of 4.11's from a Nissan P31 Pintara that fit straight into a 1970 Oz Valiant diff housing......yes, it's for a Slant 6......and for the 1/4 mile.
