Does anyone know if legacy and newer r160 diffs all share the same ring gear bolt size? The reason I ask is I have a 4.44 diff with a modified Lsd and now I need 4.10 gears.I had to drill out the lsd to fit the 4.44 ring gear bolts. This will be installed in gen 1 Brat. Thanks for looking !

yep, they're the same.

 

 

the only issue you might run into is the center hole of the ring gear is sometimes a different size. I know I wasn't able to get a 3.7 ring gear onto a 3.9 diff. So you might run into that trying to put a 4.111 gear onto a 4.444 diff (if that's what it was originally for).

 

I just put an RX LSD into a '94 legacy 4.111 diff with almost no difficulty.
