Exactly what is the brake shoe "throat", and what size is it on my 1968 with manual drum brakes all around? Do the front and rear brakes have the same throat size? I've seen replacement brake shoes showing both 1" and 1 1/4" throat sizes. Thanks, Joe.

Usually, throat is the term defining the working distance from the anvil to the main structure of a press.
Think of a C-clamp, it has a movable anvil and a stationary jaw/chuck supported by its structure, aka, backbone, lack of a better term.
The 'throat' is the distance from the anvil and chuck/jaw to the backbone.
Bigger C-clamp, bigger throat.

I believe that the "throat" is the circular hole that is formed when the tops of both brake shoes are held together. Each shoe's half hole fits around the spring anchor pin bolt. Is this correct? Also, I've seen aftermarket brake shoe type 246 showing throat sizes of 1" and 1 1/4", so I'm wondering which is correct. Thanks, Joe.
