D300 is a Passenger side drop.
youll need a spacer, and a PS drop axle or a flip it.
I think Advanced Adaptors sales a kit that flips and spaces the d300 to put behind the 23 spline AW4.

I need a d300 and an aw4 before I get to this problem.

Don't know the exact dates on the spline counts, but my 90 has 21 spline.

1991 with the HO 4.0l should be the switch over point from 21 to 23 spline in the trans output / t-case input...
