Not a 8 3/4, but I have been running the Redline Heavy Shockproof oil in my low 10 high 9 second bracket car, in a Dana 60 with Pro gears and a 4 speed. Also used it for years in my 85 Mustang stickshift Stocker with a 8.8 rearend and street gears. Very happy with the Redline, but don`t spill it! it will soak into rough concrete and hang around for years, even with pressure washing.
