I am rebuilding the brakes on a 1950 chevy 1/2 ton. There is a "bar" on the rear driver side brake connecting the shoes at the top of the assembly. It is a bar with slots at the end. I was told alternately it was a "strut" for the hand brake or a "spreader" for the shoes, any ideas? Also any sources for this part?
