Suggestion for 9" carrier

[Northern Goat]

Bought a chassis from a board member recently and it comes with a 9" rear end (less carrier). I have never dealt with Fords before but I think I have figure out what carrier to buy. The car is a70 GTO which will be mainly street driven with an approx. 550 hp LS3 and T56. The details are:

Stock 9'' Complete 3rd Member - Assembled
Grey Iron Case
3.89 Gear Ratio
True Trac Differential
Reconditioned 3rd Member Case
Pinion Support
31 Spline
1330 Series Short Yoke
Timken Bearings
National Oil Seals

What do you think? Any input would be greatly appreciated. Thanks
