Look Ma, no holes! Luckily I didn't rush out to the virtual Jim Carter warehouse and pick up four sets of springs and keys. Further confirmation that not all Huck brakes are designed to accept the springs and sardine can keys.
Huck backing plates never had holes for spring retainers. The Huck spring retainer hooks into a small piece of a 90 degree angle metal spot welded to the backing plate viewable only by removing the drum.
