Bolt and Nut Part numbers

[Binary_Jihad]

Hey guys, I just found out yesterday that the shop that did the swap on my car didn't use very quality bolts to put the turbo to the exhaust manifold and the turbo to the O2 Sensor Housing, so I need all the bolts to connect those back and get my car running well again.
need a total of five for the o2 sensor housing and 4 for the exhaust manifold flange. Does anyone know the specification or part numbers?

edit* this is for a S13 SR20DET Redtop

Why not just take the bolt's you've got an go to a local hardware store.
Just see whats the same size and but some nice stainless steel ones.

Or, if they don't have what you want, you can get almost any screw you could think of from www.mcmaster.com
