NOTES: NOS brake backing plate with shoes and springs. This is a complete unit. These assemblies are correct only for the early pattern Ben-Hur trailers, Model 41-120. The axles and brakes were later standardized for all manufactures using a 5-hole bolt pattern. Unsure if this is the left side or right side, but I believe what we have are the right side only.
