Yup, and if it does not have the correct Grade 8 fasteners on the carrier key, that's easy to remediate as well. Robb Jensen taught me how years ago. A lot of people use the cheaper YFS fasteners ( which should stand for You F**king Suck). They are cheaper steel which is not as resistant to the corrosive effects of hot gas, and lack the small teeth at the bottom of the fastener that grip the material on the top of the carrier.
Just remember the spec is inch-pounds of torque, not foot-pounds.
If you need some fasteners, just let me know, I'll mail you some of the correct ones.
