Early A Body fan shroud EBAY Link

It is for the 22in by 17.5in (I think it is 17.5) That is the size my 65 273 car came with.

What size is this, 22" or 19"? They made 2 different metal shrouds for the early a-body, both are pretty rare. I had both, didn't even know the one was smaller till I compared them. I believe the 19" one was used on some 273 2bbl cars with A/C and slant six cars with A/C.
