3418623 exh. manifold

I'll have to look?? I just didn't know if you were looking for a particular year/date?? Some folks want an exact month/year.

My drivers side is stamped 1/15/74. It’s for a 360 but same as 340 in form and function. It would be a bonus if the date was the same, however, it’s not real important as the date stamp on the inside of the RH manifold.
Thanks
