Well,
The 1935 and the 1940 front end looks alot alike, BUT the 1940 front end will have Hydraulic brakes, and a thrust bearing between the bottom of the axle boss and the spindle,.... this is the spindles you want, The 35 has Mechanical
brakes and no thrust bearing,.... but they both have 5 on 5.5 bolt circle, the bearing takes a lot of load off the spindle and will give you better steering.
