Missing stud and nut on exhaust manifold pipe that connects to exhaust
pipe going under car. Anyone know the thread sizes for a
replacement. Would consider using a bolt if I cannot find replacement
stud. Any ideas?

Thanks, Alan

I think SAAB has traditionally used M8x1.25 studs. You can get them
at regular parts stores. They are grade 10.9.

What does the 'grade 10.9' mean if you don't mind me asking? I presume it's
something to do with the tensile strength and/or hardness of the steel?

Yes. Metric strength grade. 10.9 is about the max you will find in a
normal hardware store. US grades are numbers like "5" or "8" (an 8
being the same as a 10.9; a 5 is the same as the next common metric
down, 8.something).

A few places sell exhaust stud repair kits. I bought one from parts for
saabs in the uk not too long ago.
