Need source for brake parts

[bigmoe]

I took over a project with a square body 12 bolt rear end. It was from a 6 cyl truck with 2” brakes. It came with new drums, shoes and cylinders still in the boxes. I bought a hardware kit but there’s still some stuff I can’t find like the pins that go in the cylinders to push the shoes. The metal slotted piece that goes between the shoes at the top (strut). The e brake lever the cable attaches to and the brake self adjuster. Anyone have a source for these?
