I haven't done this, so take it with a grain of salt - I seem to recall that 930 output stubs have the same larger diameter (108mm?) and larger bolt fittings (M10) that late-style G50 stubs/axles use (as well as early - coarse spline - 915s, except that these used 4 bolts/2 pins)).

If that's right (and the respective axle lengths are in the ballpark), you might be able to use G50 axles for a 911.

These don't bolt up on the wheel side; the separate drive shaft 901-332-232-00 that engages the 911/930 wheel hub on earlier cars is part of the axle; nominally non-detachable. Remove the drive shaft in the banana arm, and the CV only gets bolted up on the gearbox stub.

If you went with M491/930 G50 axles without the attached spline, you'd need to swap the wheel drive hub to match the axles.

It's also possible the CVs will interchange on the axles. That could mean you might be able to fit a 930/G50 CV on a 915 axle, or a 915 CV (e.g. the wheel end) on a 930 or G50 axle.

At least you'd always know what was going to break if you did that...
'77 S with '78 930 power and a few other things.
