3.50 ratio non posi. Small bearing. Can't remember whether it has 10" or 11" brakes. Original vehicle was low mileage used by security guards on plant site so no off road abuse. Totaled due to engine fire and I bought it at at auction when the plant was shut down in the early 70's. Still mounted in frame on original leaf springs. Also have set of 4 of the optional 16x5.5" wheels that were evidently a fairly rare option. 5 on 5.5" bolt circle.
They can be had complete brakes and center section with the 3.50 open like yours for $150 around here. Don't know about the wheels.
Early 9" Bronco rear axles are like gold around here, guys building Model A's & Deuces, especially traditional styles want the Bronco because it's the perfect width to fit under fenders or hiboy style and the fact that they have a 5 on 5 1/2" bolt patter that matches the early Ford drum brakes. They are getting had to find and will bring a premium, I sold a nice complete '67 Bronco rear axle for 500 bucks just a couple of months ago. HRP
