Small bolt front disc options for a 65 Valiant ?

I too went with the scarebird setup. Big plus is the suspension doesn't have to be broke down. I had already rebuilt the front end before I decided to go with discs. I did go with longer studs, but I don't know if that was really necessary. The thickness of the rotor is close to the thickness of the brake drum it replaces. I am very happy with the scarebird kit.
