It butts right up to the ring gear immediately behind where it meets the pinion.
But, I’m not sure it makes too much difference on a low-pinion rear setup - especially on a thick cut 14 bolt ring gear. Carl told me he tested the deflection of a low pinion 60 gearset when applying 2,000 pounds of torque. It’s on his YouTube channel and is pretty cool how he did it. On the drive side of the ring gear teeth (ie going forward) he saw only 2-3 thou deflection. On the coast side he saw 25-30 thou deflection. That is why the load bolt makes a big difference on a high pinion rear, or a low pinion front, as going forward - where most of the torque is applied - is on the coast side of the ring gear teeth in those configurations.
So I’m thinking it through. Although it sounds like a fun little project, there may not he much benefit in my case. Also, I still don’t know if there is enough meat left on the shaved ring gear beyond the carrier bolts for it to work.
Funny, when I told Carl I was putting Crowne gears in there, he was impressed. “Those things are the shit,” he said. I assume he meant that in a good way…
