And you're not in FL, why? lol

If the trans is a lockup, the end of the input shaft where it goes into the converter will be noticeably smaller at the tip. 998 or 999 lockup that works hydraulicly not electrically.

Now by the looks of this chart the A-998 was fitted behind the 318s.

Here's another question: Being my '89 D100 came with a 318 would this make the transmission behind it a A-998 instead of an A-904? I know for a fact it is a non-lockup transmission.

No it is a lockup version or it won't have that electric plug in switch on the back of the front case. They switched to having the computer engage the lockup somewhere around 88ish
