braking situation on my cb450

[MJPriceisright]

hey all, so i had a little question and was hoping someone might lead me in the right direction.. have recently picked up a 72 cb450, but it doesnt currently have a front brake setup, so i have to do it all from scratch.. the only thing it has is the front rotor attached to the wheel.. was wondering if i should gather all the parts to complete the disc brake setup, or im also seeing people run drum brake on the front? i kinda wanna keep the disc brakes, so this is what im assuming i need.

master cylinder
brake line
caliper
random misc bolts

anything i am missing here? can anyone lead me in the right place to find these parts? i see on ebay and what not, but its usually like the brake caliper without any parts, was kinda looking to buy the whole "shibang" so i dont have to worry about the piston etc.. thanks guys, any replies are appreciated.

looking around on dimecitycycles.com, great website for odds and ends, looks like they have a master cylinder and brake lever combo.. but no caliper parts etc.. will check around on the forums as well.
