Who makes a big rotor fro TCI chassis?

Put a full TCI chassis and moved the frame rails in a little (40.5" outside) on my formerly stock 67 SS Nova. The 406 with T56 only required limited cutting in the shifter area. Put 17x315-40s in the back and 17x245-40 on the front, got lots of room. The 10.5" 82 Camaro rotors that came with the front kit now look stupidly small inside the wheels. Anyone know who's 12" or 13" rotor will fit the Mustage II style spindle. I can fab up a new brackets easy enough.

Baer brakes makes 13"rotors....maybe wilwood too.bm

This kit is designed for the TCI clip

I wonder what the difference is between the complete and the upgrade kit, besides the $600 mark up.

CPP came out with a big brake kit (13") for mustang II spindles
