Big 6 lug Brakes

[mickeymouse]

Ok, so I bought a Mcgaughys disk brake conversion for my 70. I am running 20" wheels, so the small 12" rotors look tiny.

Anyone know of a 14" or 16" rotor, caliper and bracket that will fit the spindles I already own? I could probably use the brake performance, so it's not all just looks.

I plan to convert the rear 12B as well, already found a few kits for that. I also already own the rims, so going five lug's out.
