This picture shows the 4 pieces which each adapter bracket is made of.
This wooden mock-up shows what the adapter looks like after welding .
Here the adapter bracket is mounted on the spindle. Note that I had to grind off some of the surface near the outer perimeter to clear a part of the rotor. If I had been able to obtain thinner material, this would not have been necessary.
The rear side of the spindle with the bracket mounted.
Here is how the caliper bracket looks mounted on the adapter bracket.
A complete assembly. The rotors and calipers are from '69-'72 C bodies. The bearing sizes and distances apart are identical to the drum set-up.
