All right guys, sorry for the delay, but here are the measurements from my stock non-LSD differential. It is from a 1998 4x4 KIA Sportage with 28 spline axles.

A = 6.225" (outer diameter of the ring gear mounting surface)
B = 4.650" (inner diameter of the ring gear mounting surface)
C1 = 1.555" (outer diameter of the axle shaft housing/bearing seat)
C2 = 1.555" (outer diameter of the axle shaft housing/bearing seat)
D1 = 1.175" (inner diameter of the axle shaft housing)
D2 = 1.175" (inner diameter of the axle shaft housing)
E1 = 0.810" (bearing seat width)
E2 = 0.810" (bearing seat width)
F = 0.900" (thickness of ring gear mounting surface to bearing seat)
G = 4.450" (distance from bearing seat E1 to bearing seat E2)
*H1 = 2.350" (distance from outer bearing seat edge E1 to where axle shaft would stop)
*H1 = 2.350" (distance from outer bearing seat edge E2 to where axle shaft would stop)
*H1a = 1.155" (distance from snap ring location to where axle shaft would stop) I.e. Spline length inside side gear
*H2a = 1.155" (distance from snap ring location to where axle shaft would stop) I.e. Spline length inside side gear

*Axle spline count = 28
*Axle shaft diameter = TBM (To Be Measured)
*Axle spline length = TBM ( To Be Measured)

I will try and update this post with the distance from the outer edge of the bearing seat to the end of the dotted lines in the picture posted in wd8cdh's post listed above. I believe this is the distance from the outer edge of the bearing seat to the end of the axel shaft which is also the inner most side of the differential side gear.
