Summit Rear Disc Brake Coversion Kit 11" Rotors have 7/16 hole and I have 1/2 studs!

ANYONE PLEASE HELP!!
I have the Summit rear disc brake conversion kit for my '68 and it has 11" rotors that have 7/16 holes, but I have 1/2 inch studs! Everything else fits great, but I don't want to have to drill out the holes in the rotors everytime I get new rotors.
Does anyone know the appropriate rotor that I need!! I have searched Summit, Google (which is worthless), and all of the regular car part stores (Oreilly's, Advance, etc.).
I get mostly FRONT rotor returns. THIS IS KILLING ME AND STOPPING ME DEAD IN MY REBUILD (Pun intended, and working!)
HELP!

Drill the rotors…. :)

Have fun if those are Cadillac metric calipers. Follow the instructions to a tee….

They are going to be 7/16 because that is standard for cars of that era. Get a cheap drill press from HF...

No worries, new rear brake kit will solve the problem...
Keep it in the lines!!
