Ok, so I replaced the shoes on my 74 power wagon yesterday. Waiting on wheel seals so I can repack and reassemble the hubs.

I took pictures of the brakes before I pulled them apart.

I put them together how they came off. I know there is a leading shoe and a trailing shoe. Longer shoe goes on the front (Edit:rear) But looking at both sides, they look identical (longer shoe on right). But here's the tricky part. Both shoes are the same length, but one is lower. It only looks longer. I know I'm not explainin it correctly, and it's not letting me post a pic. I'll crop and try again.
