Have a 1968 rear hub, the unit with four bolt on. How many types of brake backing plates were used ? The hub on mine has no loop for return spring. I'am in need of the cush drive holder if someone has one or will sell this hub to you.
The early ones use a spring that fits over the brake arm where it comes out of the hub. The spring then pushes against the axle and the brake arm, many of the front brakes use the same sort of spring arrangement. The later 4 bolt hubs use the loop and spring.
If you don't find the sprocket carrier for that unit I would be interested in it.
