I have a completely rebuilt rear end for a 1957 Chevy. Trying to figure out a value on it. Have been doing research to find what I need but am finding mostly 9" very expensive units. Obviously not a good comparison.

Specs on the rear end: 10 bolt, posi-traction, 8.5", 3.75 gear, 54.5" from backing plate to backing plate. Includes wheel cylinders; brake lines, shoes, and drums; and emergency brake cable.

Any input would be appreciated.
