'63 Disc brake upgrade - studs ?

Sorry about not getting back to my thread earlier.
Firstly thanks for all comments and suggestions.
Since posting i have found the listing at Pentastar down here.

Part of my delay has been in picking up the discs, but i now have them.
i'll take up the suggestion to take out one of the ones I have and then look into ordering them.
Don't go holding your breath, but when i have a solution i will complete the post and let you know what way i went.

Thanks again for all your contributions! You blokes are good!:toothy8:
