so i'm installing my stainless works lt's and i got the left side on and all of a sudden one of the studs in the block just started spinning in place so it has to be removed and replaced but no auto shops have 2012 gt studs so i was wondering if a stud from the 4.6 will fit?

 

If its spinning in place, the threads are stripped out and you'll have to heli-coil that hole first.

 

no it threads in

 

Negative my friend:

"Like all modulars, the Coyote uses exhaust manifold studs, not bolts. Enlarged to 10mm from 8mm on the 4.6"
