6 lug front disc

[eastcoastcivil]

I want to change my 67 to disk but not sure if I wan't to change the spindles. I could put 6 lug disc but everyone says its hard to get parts if you break down and thats why they switch to 5 lug. Wouldn't the only difference between 5 lug and 6 lug disc be the number of lugs on the rotor? or am I completely out to lunch?

I have a lead on a pair of 6 lug rotors and am also wondering if the caliper set up would be the same as a 5 lug and all I need is the rotors?
