Now that I've seemingly succesfully have done this discbrake-conversion on the '62, I'm going to redraw/redesign the adapterplate so I can have it lasercut again just like the one I had done for the '64 spindle. See pics below of the '64 spindle-design I once did.

I will also go on and convert the '60 NewYorker now, and if the spindles are the same, also the two '57 cars I have soon.
I will however be using fixed Wilwood calipers next for ease of parts availability.
