Brake ecentrics

Overhauled my 39 Six, engine runs great, brakes, not so great. Rebuilt backing plates, new shoes, springs, wheel cylinders, bearings seals and shoe clips. Brakes were pretty good for almost 1,000 miles but recently, brakes "howl" / squeak. Pedal seemed to get softer as well. Bled brakes again, no air.I took off the left front and found eccentric had backed away. (not the star wheel adjustment at bottom, the eccentric adjuster at about the 10:00 or 2:00 position on the backing plate). Even though it has a locking nut, can't seem to get it tight enough as after I adjust it, just a few miles later, it has backed off.
SO, looking for suggestions and, a source for one these eccentrics as I broke the the small square flange for a wrench off. I did drill the core, tapped it and put a hex bolt in, kinda works, but know I really need to cinch these down tighter
