340 motor exhaust manifolds

[CudaMoparRay]

Removed from my 1972 Plymouth 'Cuda 340 motor exhaust manifolds in excellent condition.
May fit others, please check pictures for appropriateness.
WIW? Thanks

Date codes indicate a later model (not a 1972). In addition, the driver side manifold is incorrect for 1971 - 1973 'Cudas.

Originally I was thinking of taking the headers off and replacing the "original manifolds" but according to your information it might be best to just leave the headers on as the manifolds may not be from this engine after all

If I had a good picture of the left side casting number I could tell you what it is off of. The right side is 3418623 and will work on 71-73 A B E body 340 or 71-73 c body 360. The left side looks like a A or E body because of the way the neck is curved to go around the steering. 

                                                               Hope this will Help

I think the driver's side is A Body as well

Sorry for late reply.
 
I am not sure why the left manifold has only 5 digits, there should be 7 digits for the casting #. The casting # for your left side starts with 40967-- making it a later casting. Dates on the casting I can't read.These parts and casting #'s were gathered from the original parts books.

Well it looks like, at least for the driver side, I have a real mystery that has stumped the experts 

Sincere thank you to @ply64post , @1972V21Cuda and @anlauto for the good old college try
