I did something stupid

No Mopar axle came with 4.11 gears.
4.10 wasn't even factory installed in an 8 3/4" axle from what I've read, only aftermarket gears. The Dana 60 could be had with 4.10s though.

That is why I asked. I had 4.10 in an 8 3/4 for about a month, then traded them out. I see it has 3.91s.
