Almost finished my post, and then accidently closed my tab, had pictures and everything too 
Anyway,
Here are some pictures for people in the future wondering where the speedometer gear connects to the 1345 warner transfer case
And no part number on the drive gear, but there is a R and a 19, I am assuming 19 is for the teeth
Thanks Again,
Devin

Ahh I see, there is still some back work to do with Tirerack, I assumed you only had to do that if you aren't running the original tires, I figured since I was running the original tires they should show up in the parts manual, and I wasn't finding them cause I was looking wrong. Can you tell me what page you used for the gear?
Also don't know if you saw my other post, think I snuck it in alittle bit after yours. Anyway I did indeed count the teeth and it came up as 19, so do you think that maybe why I wasn't getting any movement on the speedometer, or would that just throw off my actual speed and maybe the PO just replaced it with the wrong one, possibly wrong car or maybe for transmission 2wd model? Can you tell by my pic

The # usually indicates # of teeth. But, that MAY be the wrong gear. Take a look at this page. Remember I said you need a 2A, but your gear may be the 2B. Any chance the R is a B? EDIT: No, it is an R, for sure.
I got the gear info from the first of the pic's you posted.

Just to clear things up,
I am locking for the drive gear, not the driven gear? correct
D0TZ 17285-A
not C0DD 17271-A

Nevermind it is the drive gear that I want, figured that out after searching them both and finding the related pictures
Couldn't find anything online, they all were different part numbers like C0DZ OR C1DZ, so I messaged Chris, if not when I get up tomorrow I will call around to the dealers in my area
Thanks Again Gary,
Devin

NO! The drive gear is inside the t-case and you have to disassemble the t-case to get to it. The driven gear is the one on the end of the speedo cable that sticks into the t-case. My mistake to have included the drive gear's #. You want C0DD 17271-A. Sorry for confusing things.

Yes, I'm confused...
IIRC he (Digital) can hook uup a drill to the driven end of the cable and make the speedometer work, correct? That would imply that everything there - driven gear, speedometer, cable - are in good working order.
So... do we need the C0DD-17271-A thing?
BTW I despise looking up speedo gears in the parts catalog, I seem to have problems for some reason and Bill (ND) smacks me around for it.
But looking for a supplier of a part number is easy, just plug it into partsvoice.com and see what comes back.
BUT.... in this case, make two entries....
C-letter-oh-DD....
C-zer0-DD....
The correct variant is C-zer0-DD but they get mixed up in the computerized records (I blame lack of quality control + OCR software).

I'm hoping it is the wrong one, the "b" in the drawing. See the flutes shown on the b drawing? Look at the pictures. Kinda looks like it may be that one. And, if it is the wrong one it may either be too short or not large enough in diameter.

I would think you'd be happy that you found one! Or, rather, a place that claims they have it.

Hey look what I found out
After looking at the top chart if you match up C0DD 17271-a with its part number you get C0DZ 17271-a, and when I put that in parts-voice I pull up more dealers, so I am going to see if they will deliver it to my local dealer tomorrow morning and get a price. But that c0dz part number matches up with your link, and I am curious why your link lists the 16 tooth with a 3.27 ratio??
Thanks Again,
Devin

Also, if you look the only other 19 toothed gears are the 2a and the 2, and my gear I pulled out doesn't really look like a 2, so if I have a 2a with 19 teeth and I am replacing it with a 2a with 16 teeth shouldn't it still work, but just not accurately, or Is it possible there is a reverse direction, I skimmed something like that with the c0dz part number but it was referencing a mustang
