D44 / D30 differences?

Maybe I'm losing it, but I know a few days ago I read a thread that detailed the difference between the Rubicon D44 and the D30; I'm pretty sure it described the inner/outer sizes and all that good stuff, including whether the Rubi D44 uses D44-sized parts...

I've spent all #$%$# evening trying to find it again and can't - I'm not positive at this point that it was even on :dunno: Anyone?
