Looking at a diff from a fellow member, its from an EA-ED from the info ive been given, but has been converted to 28 spline 4 pinion when rebuilt.

Im not sure what model diff housing it currently lives in, but based on the info Ive got, will this fit in an AU series 2 diff housing if I removed the hemisphere with the gears on it and slotted it in? Coz its the ratio Im after and lsd, so would be killing 2 birds with one stone.

Ill invite needforspeed to leave whatever other info he can supply.

i belive it would (if its been converted to 28 spline) my brothers au is 28 spline.... so yess
