Exhaust Manifold Double-Ended Mounting Bolts

[Basilius]

I need to replace the two double-ended M10 mounting bolts from my exhaust manifold, but I can't find a part number or replacement bolts. Does anyone where to buy replacement bolts, or has anyone come up with a different solution for replacing these bolts?

Those are not bolts, they are exhaust manifold studs.......as long as the cyl head end matches the thread dia & pitch one can select the stud & nut they choose
