Drum to disc swap

I've got Wilwood brakes on all four corners of my car, but I had already converted my car to the 73-76 disc set up before. Go for the heavy duty vented rotor kit on a street car. I can't offer much more advise than that though. I would think if your car had 10" brakes on it then that would be the set up you'd need to get.

But look it over first, do the backing plates appear to be modified? Were the drums redrilled? If not I'd say it's a safe bet you got the right set up.
