What year is this hub and stub axle?

[Todd Simpson]

The car is a ‘71, but the trailing arms are 74 and later Al.

CV joints are the style with four bolts and two pins.

I want to replace these on my track car to be safe.

Thanks,

Coarse-spline 108mm flanges with 4xM10 bolts. Some have pressed out the pins in the gearbox flange, tapped for M10 and removed the wheel-side stub axles. Then late G50 attached-stub axles bolt straight on. Otherwise, you will need the early stub axles if keeping the 4xM10/2 pin arrangement.

911 hubs were the same for many years, like '69/'70 or so through '89, so should be fairly easy to source. PET has the part #'s - pretty sure as soon as they dropped tor the dual bearing/spacer the early cars had for the single bearing, they were all the same.

930 hubs reverted to the dual bearing setup, but PET shows different bearing sizes from the early cars, IIRC.
