B8200 Owners. Help!!!

I have a B8200 4wd and I had my pinion seal on the front axle start leaking well after tearing it apart I found the reason it was leaking was because the bearing were very loose so I went farther into and found that the teeth on the pinion were badly chipped so I started looking for a good used one as it seems most of those parts are not available new. I located a place in Texas that said they had what I needed so they shipped it to me.
Here's where my problem is. The pinion they sent me came with the bearings a collar between the bearings and a triangular plate that has the seal in it and the plate bolts to the housing to hold the pinion in. My tractor has a much longer pinion that goes in a tube that has triangular flanges on both ends. They are claiming I don't have a B8200 but the tag on the left side clearly states in English that it is a B8200D.
Here's where I need help. I am needing someone with a B8200 to tell me if they have a cast iron tube bolted to the axle housing that is 4 3/16" from flange to flange or if they just have a thin plate about 1/2" thick bolted there.
Thanks in advance to anyone that can help

Hopefully this helps

I'll take a picture of the part they sent me when I get home this evening.

I did get the pinion and ring gear from them but it's all worthless to me since it won't fit my axle.

This is what I was sent. The splines aren't even the same size as the ones on my drive shaft and it's just to short. I didn't have the pinion installed in the tube in the previous picture but that's how long the pinion needs to be for this tractor. I talked to the guy today and it seems like he's trying to help me figure out what's going on but I think he thinks he has the right parts for my tractor and I'm thinking he's wrong

The part you are showing is the part off of a b8200D.
Post a picture of the other one that you got.

Another note: did you also get the ring gear with the pinion?
If you didn't, the pinion is worthless, they have to stay as a matched set.
