Correct Bellhousing for a 67 BB

matthon,
Sorry it took me a while to get back to you here.
The casting # 2468372 is what is on mine. It is
the original as I was the first one to unbolt it from
the factory. The other casting #2536945 may also
be correct and just from a different foundry? So
the first one is the original for my car but can't
say for any others.
Take Care,
Rick
