I don't think I've seen anyone break a diff on here unless they're pushing like 400+ whp. If it's broken it's not drivable right? I'm surprised your not more urgent for a solution...
At $1k+ for a quaife you're only a few hundred away from a cusco and a few hundred more to os giken. I'd say save yourself several hundred bucks ($1k?) and grab a used or junkyard diff based on what you posted or go all in. But I don't have experience with a diff on this car.
