Roll pin:
So I had scooped a third from Harvard a while back and it ended up being a v6 third. An 80 front is a hybrid of an axle. Reverse rotation ring gear (high pinion), 4 cylinder spiders and carrier style with v6 carrier bearings. It will take a v6 carrier that is full case and runs the double center pin and 4 spiders.
Now the front diff should have he best of all worlds of yota.
Also solved another myth, a yota 8" is the same diameter as a "8.4". It's the carrier that's so much better not the ring gear.
