I am going opplinger long box close ration (on good advice) and I have just assembled the mk supra diff kit on my newly rebuilt bara 3.9 supra diff......new bearings, seals bolts, paint and reset the LSD. I will do a thick wall front diff but bara is getting 10 of the cr diffs like Wenny runs but the cost is around 3k for these and don't think i will need it.

As for the hydraulic clutch I think Reyland sell them in 2 kits depending on centre push or arm iirc
