I ran into that scenario with my '50. My conclusion is that some of the Huck brakes did not use the center hold down springs and therefore had no 90 degree tabs nor holes in the backing plate for them. Given that the shoes are anchored relatively solid at the bottom pivot pins as apposed to free-floating as in the Bendix design, perhaps it was determined in 1950 by GM that these springs were actually unneeded. I have run mine for 4800 miles without any issues. No bad noises, and during an emergency stop the truck makes all of the noises of a truck stopping (squealing tires), as it comes to an eventual stop in a very straight line. Just as designed, albeit scary.
