Removed my exhaut manifold because it's cracked and some studs on the top and bottom of the catalyic Converter broke. Also a stud for my exhaust pipe that goes from under the intake manifold to the exhaust manifold broke. Been trying to find replacemnt studs, but not going well. Need m8-1.25×40, m5-1.0×40,& m10-1.5×40 If i buy replacement studs with different threads, with they fit properly without breaking? I'm just trying to find some that will fit.

 

Try McMaster Carr.

Maybe some real mechanic can tell you what kind of steel you need.
