cwcarpenter98, my wheels are definitely for drum brakes; those pics are very helpful. Thanks!

For now I expect I'll stick with all drums but switch to a later 60's dual MC to use with my refurbished Midland booster.

Apparently the later MC needs a longer pushrod from the brake so I'll have to sort that out.

You can buy either a deep or shallow bore master cylinder. Depending on which Booster you have will depend on which master cylinder you want to buy.
