Hope these will help ya. The shaft goes through the cab doubler on the right side of the picture or the driver side and there is a washer and cotter pin that retains it. On the left side you can see the clevis for the rod that goes back to the cross shaft and the single bracket that holds that side up.
The whole assembly with all of the parts for the parking brake is laid out after restoration in one of the pictures.
I’ll just post one link, you can scroll the other three pics:
