I am sure someone with a late model will chime in here shortly but I believe you are correct in thinking the third member is a 8.5" 30 spline unit.

Yes you have 30T axles. I believe your axle is actually 8.625" but 8.5" ring gear is fine. I heard some nonsense about needing a spacer but I don't know if there's truth to that or not.
