[SavageC20]

I am replacing the brake shoes on a dana 60 axle out of a 1970 c20. The last guy that did the brakes had both primary shoes on one side and both secondaries on the other.

I got a new net of shoes from Napa but the friction material is the same length on both sides just positioned differently. I am not sure which one would be considered the primary shoe. Did they make these new shoes incorrectly?
