the 140 ovolovs are starting to pick up in value a shame to rape it for a diff unless its too far gone body wise. The dana 30 is a very heavy unit defeats the datsuns lightweight qualities. Whats wrong with your diff or are you planning a monster engine?

Sounds like a good plan. Is that the Dana 30 differential? There's been talk about it the 240 diff (which is narrower), but I don't know that anyone's done it

Is that Flang-to-Flang measurement?

I've got a 68 Volvo 142s sitting in my garage that I won't be using anymore. The rear axle has disc brakes, a dana 30 diff and is 1350mm (53").

Seems like the perfect axle upgrade for rear discs and an LSD upgrade option since I wouldn't have to modify the axle length at all with high offset wheels. I haven't seen anything on this site about someone doing this swap though and so I figured I would ask as there is maybe a bad thing I am missing.
