Default Part number for exhaust flange bolts/nuts?

Having replaced my blown 2.8 with another I find myself looking for small parts here and there as I reassemble. I need the exhaust flange bolts/nuts (3 per side). Not the exhaust manifold bolts (to the block).

Anyone know the parts numbers and sizes?

Many thanks

Ok I found the flange bolts I believe, ContiTech W0133-1642106 8x12. Does that sound correct?

The next part are the studs, at least that's what I am calling them for now. One exhaust manifold has all three intact, the other side is missing two (like they were unscrewed from the flange entirely when the motor was taken out. Any ideas on the proper name or part number for these would be appreciated.

Click the link above- it will take you to the studs for the manifolds.

The other flange isnt a nut and bolt its a stud as well.

Parts came and they are absolutely incorrect I ordered the studs you recommended as well as another part number that looked similar. Both are too large to screw into the exhaust manifold flange.. what to do now?

Hmm I pulled those part numbers directly from ETKA. Whats the measurement?

They should be M8 X 25mm.

I will measure them, the length seems ok, they are just too wide to screw into the flange. When I hold them next to the studs that are still there they are a good 1mm too thick.

That's really strange. Unless we sent you the wrong part and obviously we'll make it right if that is the case.

Do you have the orginal packaging the studs came in? Or atleast a sticker that had the part number on it?

I can look up those numbers and see if it was our mistake.

Do you have a 12v or a 30v V6? I'm not sure if it makes a difference but I'll definitely double check.
