Not trying to hijack this thread but incase someone is looking for (4.11 ring/pinion for a 9" , not sure if it matters or not but I have 28 spline) I just removed this (see photo) long story, no one believes me that (02) different size gears were installed (4.56 in front and the 4.11 in the rear) so I had to switch one to match the other and ended up going with the 4.56. If you would like to hear the whole story see me at the Bash.
If your interested in the ring/pinion let me know and I can bring it to the Bash.
