try this: http://www.ifsja.org/tech/figures/db.shtml
or the Novak links--they deal with the stamped case numbers you have and the physical diffs:

AFAIK The D20 has a center rear output (behind the input) and the D18 has the rear output on the passenger side (behind the front output). Also I don't think the D18 ever came in a FSJ.

yup its a dana 20, so now my other question would be, is it possible to take the strength in gears and guts of a d300 and swap them into the d20 so that i can mate it up to my th400?

no,the d300 case is dimensionally different. even if you could fit the gears into the d20 hosuing,youd need to find a d20-style "bull gear" that would be compatible with the other inner gears. this gear does not exist that will fit the th400 factory d20 tailsahft(15 internal splines)

the spicer 18 wont fit for the same reason(unless you rebuild it with the d20 gears) and you even have to be careful mix-n-matching d20s,as there are 2 different pitches of the cut on the angle cut teeth.
