Need the casting & part #'s for 71 340 ex man, A bdy?

What are the correct casting and part #'s for 1971 340 A-body exhaust manifolds?

Thanks!

Drivers PN 2863552 cast # 2863553

Pass PN 3418624 cast # 3418623

There's a list that has been floating around on the net for years that is so messed up it's not funny. Those numbers are out of the parts manual.

the look of the driver side is different in 71 than the earlier ones, it does not have the numbers at the top they are hidden when on the engine

Thanks!
