difference between subaru td04's?

That's interesting, the only 13t's seem to be new ones, the 12t's on the other hand are very popular:

Does anyone know about the 12t's?

Also, what do you do when it doesn't show it's type like this one:

Good price but it doesn't say which type it is although it says it's front entry which I believe is good.
