I have been planning and researching the brake setup for this build for a long time now. Maintaining 6 lug has made it interesting to source parts.
For instance, there are a couple people making 5 lug hubs that fit the 73-87 spindles but nobody makes them in 6 lug because there is really no demand for it.
My solution was to get cpp 6 lug conversion rotors and cut the rotor off the hub portion.
I did some measuring and found the thickness of the casting for the hub section to be 0.75" so I scribed a line all the way around and the cutoff wheel made fairly quick work of the cast.
I still need to spin them on the lathe to true up the cut but I essentially now have 6 lug hubs that will allow me to use slip on rotors.
In hindsight the better solution here would have been to design around a more common spindle that had 6 lug options available. I think something that uses a standard gm 6 lug unit bearing would have been ideal.
For now Im going to continue with my current approach but I may revisit this in the future.
The rotors Im planning to run are pretty interesting and should be in this week.
