1978 Cordoba rotors?

Hi, are -78 Gordoba rotors always 11,75? Im ordering rotors from rockauto and cant find the info on the ones im looking. Any help...? These are the ones I was looking at https://www.rockauto.com/en/moreinfo.php?pk=6162318&cc=1062717&jsn=541&jsn=541

I'm assuming you're trying to upgrade from the A-body 10.87" rotors? If so you'll also need the taller caliper brackets so the calipers will fit properly, in case you didn't already know... FWIW I plan to do the same to my '70 Duster (has '73-up BBP brakes) at some point.
