WTB 7.65 3.23 ring gear and pinion and posi

I'm looking for late 3.23 ring gear/pinion and G80 posi center section. I'd like to get package deal if possible.
Looking to put my ZQ8 back like it was. Previous owner put 3.08 non-posi rear in it and I'd like to put it back like supposed to.
Thanks,
Ron
