I decided to crawl under Brutus. Wasn't going to let a little ice stop me. This is the moustache spring. It's purpose is to hold the inner shoe away from the drum when the parking brake is released. You may be able to retrofit one if your truck has the provision for the right side (of the spring) attachment screw. You're right about the adjustment knob on my type of handbrake lever. I must have had a senior moment.
