Default B300 C120 rectifier replacement.

Hello all,
I intend to replace two of these B300 C120 selenium rectifiers with two of these new ones. But which half of the recctifier is a pair of terminals? Is it left/right or top bottom?

Sorry for the layout order of the pics, can't work out how to move them.

By the way, I am aware that most of you are thinking that if I don't know the answer to this I probably shouldn't be doing it, lol, but could just do with a quick answer to this as I am not too familiar with rectifiers. Thanks.

The sine wave symbols on the selenium rectifiers are equivalent to the AC connections on the silicon replacements. How AC gets connected doesn't matter. Both the OEM and replacement parts have + and - minus marks. Those indications must be followed.
