No,

Easy way to separate the rotor from the hub `if you need rotors is to use a oversize drill bit and cut the tops of the rivets..Then use a drift to drive the rivets out......Next, drive the studs out to finish the separation hub from rotor......Just reverse the above procedure. The studs will hold the new rotors to the hubs.....You may still need to true up the rotors with a parts stores or machine shops rotor cutting machine.....

You don't need to "drive the studs out" - just the rivets after you drill the heads off. If you are reusing the rotors, mark a stud and a matching place on the rotor so you can put them back in the same place.

I went through this recently with my dad and his '81.

What was the engineering idea behind the rivets? What a pain in the butt!

to keep them in place going down the assembly line.

Do you need to replace rotors? They seldom fail. The factory assemblies were riveted to the hubs to allow machining of the rotors for run out tolerances.

If you replace your rotors, you will need to mike for run out. Calipers will keep the rotors in place without rivets.

Measure the rotors. If they make spec, don't remove them.

if your gonna seperate them, mark them so they can return to their orginal hub and orientation.
cheap way of keeping the factory run out orginal,
Best to leave the fronts riveted. Rear must be removed for service.
