800A Front brake questions

[NorCalDiesel]

I am going to r&r the brakes on all four wheels. I looked at the front first because they were completely worn and pulling. When I pulled the drum I noticed the wheel cyl pins were at an angle, as if the brakes shoes were the wrong type. I have pics below. The drums are in great shape. They have never been cut and are smooth. The brake shoes on there now are autozones that I picked up a few weeks before while I happened to be there. They are identical in fit to the ones I took off.

I am looking to get the correct brake shoes, wheel cylinders and master cylinder.

Thanks for the help,
