They look like the Tie Downs that I have on mine, they use Chevy Nova pads. If they are Tie Downs take good care of the rotors they think they are GOLD, I spent hours in my local parts house trying to match the offset N/G they are custom for Tie Down. When mine get bad I will shim in or out to get an off the shelf rotor!!!!!!!!!!!!!!!!!!!
Post a shot of the coupler the TD & Kodiak's look quite different!
I just looked to see if I still had the box with the Nova numbers, I doubt id Novas used many different styles.
