i am in the same boat. i have got my hands on a vl turbo 28 spline diff for $200 (non-lsd, but that can be fixed with a $100 minispool), but i am considering using the hilux diff as it has 30 or 31 spline axles. i think i can trust the vl one as is used to have one and never had a problem. my ute will be running a four link setup with either of these diffs.
