Early A fan Shroud

The more I look at the shroud on eBay, the less sure I am that it's the right one. Here's a couple of pics of the eBay shroud & some pics of a member's shroud. Not the same are they? If the round hole on the eBay shroud is 20" like he says, the shroud looks like it would be for a 26" radiator. Sounds from the description like it might be too wide.
