R33 Gtr Drive Shaft & Side Flange Not The Same

[[200]]

I recently bought a set of R33 GTR drive shafts and a R33 GTR diff, both separate sales.

I was unaware that there would be any fitment issues but when I went to put the drive shafts against the diff side flange they don't fit, the outside of the drive shafts is about 10mm bigger so none of the holes align.

Is anyone able to tell me what I have ? Would the reason be that I have a V-Spec diff and non v-spec drive shafts ?

Pic for reference ...

Thanks

The big ones might be R230 ones from a Z32. Just guessing.

Looks like you might have v-spec shafts, I've got non v-spec shafts on the floor in the shed and the outside diameter that you've measured on the diff is the same

I thought it would have been something small like that.

So i'll need to find non v-spec shafts
