Exhaust manifold to exhaust flange nuts. (2 Viewers)

I seem to have lost my exhaust manifold to exhaust flange nuts and dont know what size they are. If anyone knows please let me know so I can pick some up.

Thanks,
Drew

It depends on what year your vehicle is...but, those nuts, and the matching washers and studs are kinda special. Every 3 or 4 times I have the manifolds off, I replace the whole set with new OEM.

The ones I have seen are M10 x 1.25. They are not just an average nut. They are about $3 a pop at the local dealer.

Where I live there is a shop that sells extra-long brass nuts for that application and they are far better than OEM in my opinion.
