If you are talking about 98+ 6-speeds, they will not work. I actually tried it. The input shaft is about 1" too long, the bellhousing has a totally different bolt pattern. The LS1 flywheel also has a different bolt pattern. I ended up trading my 99' T56 for one from a 95'. You can use any T56 from 93-97 only.

There is a full write-up on how to swap a T56 into a thirdgen in the tech articles section of this website. You can also find more info by searching the Tranny/Drivetrain forum here as well.
