Spindle ID as nothing fits?

I have a 1973 Duster with larger ball joint control arms & SBP wheels. I,m fitting up Wilwood brakes & the caliper mounting braket wont line up on the spindle.

I have checked the Wilwood kit & the braket part number is correct, I, starting to think that these spindles have been drilled out to take the large ball joints.

What spindles do I have?




As you can see below the mounting braket is not even close.



The kit number is 140-11019 & the spindle is completly different in their assembly instructions

These are the drum brakes it came with.


Help me sort this out as it's doing my head in.
