Front and rear disc brakes conversion questions

[abadsvt]

Hello All! Here is my cituation. I bought a set of wheels with 5x4 3/4 bolt pattern. I have decided to upgrade my brakes and would like a 12" or larger front disc brakes and a similiar size rear disc brakes. I already bought a set of drop spindels for my truck so i am not sure if that matters. I don't know brakes and have been trying to do my homework but all of the threads on brake conversions were for 5x5 bolt pattern. I understand that i can have them redrilled but wasn't sure if i can skip that step and just buy a set already made for 5x4 3/4 bolt pattern that fit my spindel. I don't want to spend more than 500-600 if possible. Also i don't mind fabing up a bracket for the caliper. I would like to have some corvettle calipers if possible. I like the writing on the side saying Corvette. I know it is stupid but think it would look sweet. Thanks Josh
