Just curious if anybody knows whether or not The 2 pictures shown below are interchangeable. I'm looking for a right hand exhaust manifold for a
1966 oldsmobile tornado. The pictures look super similar. But they do have different part numbers and I'm not sure if they will bolt on and line up correctly. Thanks
PN:387992 and 395752

 

387992 is the original 1966 Toro passenger side exhaust manifold casting.
395752 is the 1967-71 Toro passenger side exhaust manifold. It superseded 387992 in the parts network and will fit fine.

 

Thank you!
