irs center section, t bird work?

Hi all, i picked up an irs from an 03 cobra, only problem was that the center section isnt salvagable. Does anyone here know if the centers section from a tbird irs will work in its place. I do realize the cobra is a 31 spline diff, tbird irs parts are a dime a dozen here, I can swap out the 28 diff for the 31.

Update, pulled out a cast iron center section from a 90's supercoupe, v6 supercharged car. The housings are identical, except for it not being aluminum. I also traded out the 28 spline carrier and gears in favor of a 31 spline 3:73 geared unit that was in an explorer that was next to the car., maybe this info may help someone down the road.
