Hi
milo,
I wasn't sure which studs and nuts you were referring to (manifold to cylinder head or manifold to downpipe) so I've listed both below:
Stud, exhaust manifold to cylinder head (x10) - 24418771
Nut, hex., self locking, M8 x 13, exhaust manifold to cylinder head (x10) - 11516076
Gasket, exhaust manifold to cylinder head - 9230949
Stud, M10 x 25, exhaust pipe to manifold (x3) - 11100462
Nut, hex., M10, exhaust pipe to manifold (x3) - 90570845
Gasket, front exhaust pipe to manifold - 24409332 or 24454112 (not sure why two part #'s are listed)
Sensor, coolant temperature gauge, thermostat housing - 15326388
Hope that helps
