1977 Chevy Cheyenne Rear Brake Drum Torque

Neither. The nut that holds the brake drum on the rear axle housing.

Thank you for your response. This truck doesn't have a Jeep axle. It is the original axle. The nut doesn't stick out passed the drum, it is recessed. The drum had to be removed to gain access to the brake shoes to replace them

No, there is no tag on the axle. I know the axle is the original, because we purchased the truck new. After unbolting the axle from the brake drum and sliding it out of the rear end housing, the brake drum was still attached to the rear end housing with 2 nuts, one of which was a jam nut. Both nuts required a spanner socket to remove them in order to remove the brake drum to gain access to the brake shoes. I need to know how much torque is required to tighten the 2 nuts that hold the brake drum on the rear end housing.
