1955 Chev Truck front disc brakes

I have a straight axle out of a 1955 chevy truck that I am trying to put disc brakes on, I have tried a couple of rotors but the spindle hits the rotors braking surface. Is there an adapter or something I need to get the rotor to work on there with my caliper adapter?

 

Five-lug or six-lug?

The five-lug kits usually have a stepped sleeve that that goes on the spindle, and provides a surface for the seal and for the bearing race. It stops the disk from going too far onto the spindle.

The six-lug kits use the original hub and the problem would most likely be with your bracket.

 

I just got the axle with no drum or anything on it,,,I will try to get a picture on here of the spindle and caliper bracket because I am not sure what it was originally

 

I got my pictures, can't get them uploaded on here,,Is there an easy way to do it?
