no 9" rears on the A body 8-3/4" from the factory, 10" only, small bolt pattern only. There were no large bolt pattern A body 8-3/4" rears from the factory.

fYI I don't think those drums are made anymore. I needed a new pair and couldn't find them anywhere.

10"

Just saying 10" isn't enough. They're 10x1.75" for the stock A body 8 3/4, as already mentioned. It's an important distinction because the 10x1.75" are small bolt pattern. Big bolt pattern drums are still 10", but they're 10x2.5".

And, at least at the moment, the 10x1.75" drums are not being reproduced anymore. There are still some out there on eBay and the like, but if you're planning for a daily driver your best bet for the long run would converting to big bolt pattern axles and brakes.
