Wheels and Brake Questions 66 Satellite

I got the old drum brakes working pretty well but still contemplating the switch to Disc. I have 14" wheels now, did 66 models come with discs? and if they did, 14" or 15" wheels?

Magnum wheels didn't come out till 67 I believe, but I don't remember any of the Satellite's having a 15" hub cap in 66. 15" wheels came out in 67?

And lastly does anyone know of a disc brake set up that will work with 14" wheels?
