The calipers and rotors are off the 1/2 ton T1 model trucks 

Front Passenger Side Disc Brake Caliper without Pads and Bracket - GM (13545383)

Front Driver Side Disc Brake Caliper without Pads and Bracket - GM (13545382)

You need 2 of these.
Front Brake Caliper Guide Pin - GM (13539444)

Front Disc Brake Rotor (Coated) - GM (13542112)

You can also change the rear calipers to 4 piston from rear of the basic stingray corvette. Uses your existing rotor. Also requires an adapter
