I bet if you look real close to the nut holding on, you will find a "2.". I'm pretty sure that you have a 2.75 open 9" rear end.

TDM ?
Are you sure it isn't WDM ?
I've never seen a TDM rear code before.
Here's a site.

It is a 2.75:1 9" rear gear though.
All the other stuff is explained on the page I linked to
