273 exhaust manifold ID help needed

Hello everyone! Joined this site to learn a litte about the 273 V8, I happen to be dropping one in my 1950 Plymouth Suburban wagon.

With that, here is my question...

I picked up a 273 drivers side manifold, to clear the stock steering in the 50, the part number is 2465847.

I would really like to find a matching passenger side, but I need help identifying one with the correct part number. As anal as it sounds, I would like to find the correct manifold that technically matches the drivers side.

So, can someone here help me ID the manifold so I can start my search?

Thank you in advance for your help, this site sure has a lot of nice A-bodies and technical info.
