hi this may be a dumb question i need to know if the pinion and crown wheel out of a irs au sedan will fit an a ute non irs can anyone help thanks

I think they might. But the centre assembly is different. Here's some pics.
The first pic is an EBII 4 pinion single legger, and the 2nd pic is an AU I XR8 LSD centre that is IRS. Both are 28 spline.
