Volvo 1800 P1800 122 140 Amazon B18 B20 Intake / Exhaust Manifold. This will fit on a carburetted engine with standard HS6 Carbs. The intake choke plates are stuck. This is a good candidate for cutting off the intake side and making this a dual exhaust manifold only. Or just free up the plates. 

Thanks for looking
