CJ7 with AMC 20 Brake Shoes Uncertain about new ones. New doesn't match the old ones

Hello fellow Jeeper's,

This is cross posted in Forum under my proportioning valve questions. Separate issue although maybe part of the problem of rear brakes locking up.

Would like to change my old shoes since the pads are loose on the rivets. All the new shoes the auto parts stores offer do not match the ones I have in the Jeep now.

The ones I have have on there now are primary shoe number FMS-267 and on the secondary shoe the number is 3208961. The sides of the pads have printed letters which read PBB-RX-FF. I can't find these shoes anywhere.

The top of the shoes where they touch to backing plate and anchor are 1"-8/32, the new shoes are 1"-4/32. The new shoes do not touch the backing plate like the shoes that are on there now. There is a gap. You can see in the picture with the black painted shoe.

Will these new shoes fit even though they are not touching the backing plate and there is an 8th" gap?

The three that I've looked at the auto parts stores are Wagner's, Auto zone brand, and Bosch. They all have the thinner width shoe top.

Here are some pictures to try to help explain this dilemma. Thank you for any feedback, really appreciate it!
