OK got the parking brake cable in and working. Now I need to do a brake job. Attached are pics front and back. I have read about a hold down clip and spring. I don't have any currently, or are they not needed for the 1950? I see a whole in the brake shoe but nothing in the backing plate to slip the clip in. Should I rebuild the wheel cylinders or purchase new ones? also if I can get someone to look at the pictures and let me know if it is complete as is that would be a big help. thanks for the help.
