exhaust manifold stud and bolt

[SmallTownStang]

While driving today either the drivers side exhaust manifold bolt bolts fell out or the passenger side nuts. I need to know what size they are so I can buy them before I crawl under there. Does anyone know. This is a 2004 GT with stock manifolds.

the studs should be a 10mm x 1.5 mm x 51mm and the nuts are 10mm x 1.5mm
