Wow, that would be strong. Bit of work in milling the recess into it though.

It was a long time ago, so don't remember exactly, but I'd say I used the R30 ones since that's what I wrote.
I guess different models of R30's had different sized stub axles, as a few people are having this problem.
I'd take a guess that the turbo ones would be the larger ones, so you'll probably want to find the most shit spec'd R30 you can lol.

The Outter CV's I used were the 3x2 bolt pattern as per your pics

These are all the pics I could find on my PC that show the champion flange and CV

This is a late 280ZX flange, it should be the same as the R30 flanges (which I'm pretty sure are all the same). It looks like yours are the same as this, what's the spline diameter?



This is an R31 flange - it has a bigger outside diameter



280ZX spline diameter



R31 spline diameter





R31 hub spline diameter

i have dr30, s12, and z31 companion flanges, drive cups/flanges and rear arms.

and also 610(so im guessing 510 as well) arms, flanges and stubs.

the s12 turbo and non turbo are all the big spline type, and all have 3X2 pattern, with 4 stud wheels.
the z31's all have the big spline, but non turbo's are 3X2 comp. flanges and 4 stud wheels.
the z31 turbo's are 4X1 comp. flanges and 5 stud wheels.

i used z31 5 stud stubs, companion flanges and 4X1 flanges to convert my s12 to 5 stud. the arms in fact appear identical.

all the "big" type stub axles run a larger inside diameter bearing on the wheel end of the stub, but the outer is interchangeable with the 610/510 bearings.

the dr30 parts i have from a FJ20et sedan, have the small spline. these companion flanges fit the 610 stub axle.
the dr30 stub itself has the larger diameter outer bearing, so isnt a straight swap into the 610/510 rear arm.

i did some homework a couple of years ago on sourcing an outer bearing for the dr30 stub in the 610 arms.
i did find one, but the write up i did is/was on DOCNZ

in short, you "should" be able to run the dr30 stub axle, and companion flange in a 510/610 arm, if you change the outer bearing to
bearing part #?????? and change/modify the bearing spacer tube to suit. this will give you 3X2 companion flanges on the arm.

or you could run the dr30 drive cup straight on (the weaker) 510/610 stub. also giving 3X2 flanges.


NOTE: this is all from memory from quite a while ago sorry. could measure some bit up here if you want...

ok just tried this.

i have a 280zx stub. same "small" spline as 510/610. it original had the old universal 4 bolt type rectangular companion flanges.

the s12/z31 3X2 companion flange is too big to fit the spline. you know this already it seems...
the dr30 3X2 companion flange is the SAME spline as the 280zx/610/510.

both the dr30 and s12/z31 companion flanges are the same overall diameter and length hole spacing etc. just the spline is different.

so a dr30 (and most likely any r30) companion flange will fit the 510 stubs.
a 280zx companion flange will fit the 510 too, but is still the old rectangle type for UJ's,
or the later CV type ones have a bigger diamter 3X2 pattern so wont suit your CV axles.

hope this helps!

Thank DJZ and Vegie and DAN, thats awesome information

Two options i see as the chance of finding some of later 280zx axles and Cv would be like finding rocking horse shit id think.

Option 1
- Swap the outer bearing and install the larger axles (assuming the spline still fits through the inner bearing) what model vehicles could i find these in?
- will the wheel still have the same offset so all the brakes still fit?

OPtion 2
- Make an adaptor/modify 1600 companion flanges to adapt to the later 3x2 axles.

For Option 1 - for this you can use 4 or 5 Stud Z31 hubs that use the "large spline" they are getting hard to find but they are around.

Jason Pooke did simialr to this, and had his small spline companion flange splines re cut to fit onto the large spline axle stub

I have some 4 bolt "square" z31 large spline companion flanges - they are yours if you find a use for them

If possible can you confirm the size of the spline on your current hubs?

R30 companion flanges should work in your situation unless you have oddball hubs. I seem to recall that 240Zs had some sort of different hubs to the 260Zs which are the same as all the other Nissans around that period?
