Small bolt front disc options for a 65 Valiant ?

I used the Wilwood wheel kit with the Right Stuff master kit. Fantastic change from the old drums. The Wilwood rotors shipped with 1/2 inch on 4.5 inch BC installed and the 7/16 inch studs in a bag which you install in the 4 inch BC. No issues with the factory rallye rims with the hub or rim clearance. I did have to modify the castle nut to accept the cotter pin since the hole in the spindle was a little too deep inwards.
