97 Cobra exhaust manifold bolts crossthreaded - HELP

Hey guys

I really need your help ASAP.

The guy who installed my long tube headers cross-threaded the bolts. I'm going to have to helicoil them on Sunday and get things back together. I need to know which helicoil kit to get. I need to know before NAPA closes today. I'd appreciate any help! Thanks guys!
