Does anyone know if there is any difference between stock exhaust manifolds for a '71 351C 4V and a '73 351C 4V Cobra Jet for a mustang? Need to change my '73 exhaust and due to the lack of availability and cost for 4 speed headers I am thinking of putting stock manifolds back on.

They are the same. The Boss 351 is different; the exhaust flange is larger.

You need D1ZE-9431-B or BA, {left} and D0AE-9430-B or G, {right}

Be aware that right side 351C 4V manifolds are very prone to cracking.
