A body 11'' disk brakes

The 73-76 A body rotors are usually advertised as 10.87” or 10.95” depending on your source. So they get referred to as 10” disks sometimes. For extra confusion there’s also the 11.75” rotors that can be used on the 73+ spindles which sometimes get called 11” disks. Neither are really 10” or 11” disks, but people shorten up the specs and that can create issues.
